description: When I was a kid, I used to marvel at all the things that said, Made in USA on them. And, they did have a high quality to them. In that regard, to me at least, is that quality and quantity of US made "things" really started to drop off in the 70's. Which seems to coincide with when heavy industry such as steel production pulled up stakes leaving the Rust Belt throughout the midwest and eastern USA. The Japanese were making inroads with car manufacturing in the 80's and had taken over the consumer electronics production. Now all of Asia practically does this for nearly all electronic, consumer appliances, cars etc. America simply in adopting to an economic philosophy that eschewed manufacturing and industry for a service economy and financial dominance in planning the economy shot itself in the feet in today's world economy. All the skills and knowhow have been atrophied from this that cripple a manufacturing industrial base returning. That and a high cost of living driven up from a financialized economy. Even our tech sector has been outdone by the Chinese. Because they've invested and developed a huge supply chain system, educational incentive and research driven by their export and government planning for the future. Our government these days as dictated by our economic strangulation of a small government shunned from participating in planning the economy and relying on whatever the whims of the marketplace is cannot compete with the economy of scale and cost of living going on in Asia and other countries once described as 3rd world. China simply followed the historical economic patterns of what Great Britain, the US and Europe had done with the industrial revolution. The need for socializing the working class's needs for inexpensive living standards to make industry and manufacturing competitive for trade. Finance capitalism has stymied our nation. Made in the USA is a thing of the past.

description: Remember the perception of Japanese products in the 1950s and 1960s? Very similar to the perception of Chinese products today. And back then - when I was a kid - I do remember that most Japanese products were pretty inexpensive, low-quality items. But what I didn't realize was that they were working hard on R&D, making better and better quality stuff. By the 1970s, their motorcycles, cars and electronics were pretty good. And by the 1980s, everyone in America realized that because there was a rapid shift towards Japanese consumer electronics and cars. America has always made very good quality products. We've had our ups and downs, but we've definitely been a manufacturing leader. We still are, in my opinion. But we're not the only ones. Britain and Germany have also usually been up there in terms of quality, and some other countries too. Not so much the orient, at least not for tech and heavy industry, until maybe the last 50 to 100 years or so. But they are definitely catching up. Japan and Korea are there, I'd say. China is probably close. India will probably start catching up next.

To their enviable standing economically and security of their people enjoying a middle class, affordable life now. All while our middle class has shrunk considerably since the latter part of the 20th century till now. What's the deal about the Brits anyway? I'm of their heritage as are quite a few of the Anglo Saxons that make up a large portion of the US. Britain is sinking economically as we are. Along with Europe & Australia. All from the economic doctrine we all follow in the G7 countries. No other country in the 20th & 21st century has gone to war in this world than the US has.

Re: What material is the best for soundproofing?
type: item
description: With my experience fixing noisy rooms, the best material that I would say has done the job for me quite alright is the mass loaded vinyl. I understand that others might have a different opinion in terms of which material works best, but I've never gone wrong using MLV to fix issues with noisy rooms. I recently used in a new studio that my mentee started last two months and the result was excellent. All I did was use it in dozens of walls and cellings... the outcome was fantastic! So, I will always recommend using MLV instead of other materials like foam panels or thick curtains that won't be able to block sound from moving through the walls. I bet you won't you don't want to have such an experience. I will always advise that you pair the MLV with proper installation and you will figure out the difference straight away. I have used this method in many rooms and assisted my friends in doing same and it has neve failed.

Re: Sound in basement
type: item
description: The issue with concrete basements is that it makes songs sound harsh and kinda boomy as a result of the hard walls and floors. There are a couple of tips that I think you can use towards improving it, such as putting heavy blankets on the walls. I used acoustic foams on mine, and it does the job well. Also, having soft furniture and bookshelves filled with books also assist in absorbing the sound. I would ask that you start small, play your guitar, and observe the changes until it feels right.

Re: 4pi: Cabinetmaker's build
type: item
description: Excellent observations, and an excellent question. I'm glad you asked it. The "mirror image" I've always used is purely for aesthetics. There's no significant difference whichever side each speaker is placed. That said, I've always placed the ports outside, except for the four Pi model. I place the tweeters outside on that model. The reason is trivial, but I'll tell you why. It's because of the vertical nulls we discussed earlier. They are perfectly above and below the speaker if the midwoofer and tweeter are both centered. But with the tweeter slightly offset, the nulls are too. Or perhaps I should say the maxima above and below are slightly offset. They track a line drawn between the driver centers. So the upper null is a little bit towards the tweeter side and the lower null is a little bit away from the tweeter side. Just a smidge. Insignificant. Still, that's why I always set 'em up with the tweeters outboard. Back to your speaker placement. That's a great observation too. I've noticed that as well, and it's exactly what the flanking sub configuration mitigates. Try that setup sometime - I'll bet you'll hear the improvement right away, especially since you could hear the SBIR from the wall behind the speakers. Flanking subs are specifically designed to counteract SBIR from nearby boundaries, e.g. the wall behind the speakers.

Re: Does best picture = bigger projector?
type: item
description: I would argue that the issue that those early mini projectors had were the components used and not necessarily about the sizes of those projectors. I noticed that the manufacturers used weak LED bulbs, inflated throw distance specs, and plastic lenses. Doing so affected the picture quality even in dark spaces. While I think the size can be a factor ( not necessarily a big one), I am of the opinion that most mini projectors done nowadays are far more better than what we used to get some years ago. The picture quality is better since companies use better LEDS and 1080p chips in making the ones that we have now.

Her new book called, "Crime & No Punishment: Wealth, Power and Violence in America". She goes over through how most certainly is our economic doctrine that has allowed for wealth to accumulate at unprecedented levels since the 1980's, basically from when Neoliberal economics took hold. And through the capture of the legislative process through campaign financing. Which has corrupted our democracy to the point there isn't much left of it. She emphasises how corporate and big banking has managed to escape being accountable to being punished for their crimes inflicted on the public. Big Pharma, the real estate bubble collapse in 2008 for example. And the gun lobby that has made violence an everyday occurance, mass shootings a regular news happening. And privatized prisons everywhere. America is one of the most violent advanced countries in the world. Our war mongering throughout the world unabated. And a military complex that with a budget over a trillion a year now. Can't provide the weaponry to sustain our war machine for any length of time. Which may be it's only saving grace.

Re: Popular myths about tube amps
type: item
description: I'm an electrical engineer and I grew up in the 1960s and 1970s. Those were years when tubes were in decline, and by the 1980s they were probably at their lowest acceptance point. There are several disadvantages to tubes, and so I understand why they were being left behind in that era. They are large, vulnerable and relatively power hungry. They are not only vulnerable to physical damage but also to microphonics from vibration. Combine that with our rapid movement in the digital realm and tubes were getting left in the dust. My mindset tracked with those thoughts too. I considered tubes an interesting piece of history, something like the horse and buggy. I enjoyed the nostalgia of a tube radio but didn't think they had a place in the future. When I heard guitarists say things like "tubes sound better," I discounted their opinions because they also said things like "tube watts are louder than transistor watts," which I knew was nonsense. A few facts started presenting themselves in the late 1980s and 1990s that slowly changed my opinion. The first one was a realization that tubes are inherently resilient to lightning strikes and electrostatic discharge. In the 1980s, one of the things I did was to design large lightning protection systems for computers and computerized controllers. I used primary and secondary protection - Intentionally placing lightning rods to attract strikes to a known location as primary protection and incorporating surge-clamping diodes and other solid state protection devices as secondary protection on the power lines and the even more vulnerable computer interface lines. The strikes would induce a current in the control and/or signal lines, and the SCD and/or MOV devices would clamp those. I couldn't help but to ponder that a tube transmitter had a huge antenna just luring lighting towards itself, but it had a natural resilience to strikes. The tubes might be vulnerable in some ways, but this is one way they were much less vulnerable to solid …

At this point in time of our nation, judging from the graph showing the wealth distribution in our nation from such a tiny fraction of our population. Incorporating a separation of wealth and state could wisely promote legislation also in behalf of the people. The majority. And the ones in our nation that currently have little say in what favors the minority. That would also preclude extricating our legislative process towards following a revised economic doctrine. As also evident from that same graph from when the Neoliberal financialized economics was established. Adapting to an economic doctrine that has allowed over time for wealth to influence our legislative process.

So I kind of get that. I never hated earbuds but the reason why speakers are good for the family is that you can just put songs and stay anywhere around the house and still hear the sounds and beats too. Earbuds are when I want to watch movies or listen to personal songs. One can't even compare both. Speakers are simply on a different level because they serve a different purpose than what you use earpuds for just like you said.

description: I could only go for so long here before starting up my true Dungeon nature by posting some subject calling attention to these times we live. I like this young blogger for his thoroughness with his analysis. Which with this subject counters the usual articles put out on what our country's economic status is. I think that is typical of many subjects in the news too. Here Ben Norton goes over objectively with our economy with a healthy dose of interpreting data unadulterated with cherry picking. Most Americans are not wealthy. That's the 90% of the population. If you make it through this blogs lengthy presentation, you'll get an idea of how we really fare with the rest of the world. Our healthcare system, rent, insurance, child care and so many other metrics of modern living are what drags our cost of living down with other nations that may surprise some. My favorite chart he shows is one showing the wealth of the .00001% that owns 12% of the total income in the US. But it's the time period of the late 40's to the 1980's when Neoliberalism took over from Keynesianism showing the Golden Period of American prosperity for most people. We baby boomers know of it, grew up in it. And now our young generation is not part of the once American Dream. https://blog.syzgroup.com/syz-the-moment/wealth-at-the-top-0.00001-owns-12-of-us-income I think our country has lost its principles when it eschewed our manufacturing and industry away to maximize profit. And our economic system became financialized and service oriented. Its made us weak and dependent and loaded down with debt. The rest of the once 3rd world as was known is the manufacturing centers now. Their standard of living is rising. Our's is declining. You wouldn't know that reading and listening to corporate media though. This is why I like alternative media. There's no editorial board to tailor the truth.

description: Excellent. OK, then, that tells us that the drivers are hooked up properly. Crossover is doing exactly what it is supposed to do. As for the throatiness or resonance, I suggest a couple things: 1. Check your damping material. Make sure you added the sheet that spans the cross-section in addition to the ones that lines the walls. That cross-section sheet is extremely important because it traps the lower midrange better than the ones that line the walls. It should span front-to-back and side-to-side completely, essentially splitting the cabinet into two areas, one exposed to the woofer and the other exposed to the tweeter and port. Bass will pass right through but midrange and treble will not. 2. Explore the flanking-sub approach. The self-reflection from the front wall often manifests as a throatiness. It definitely causes a defect in the lower midrange if the speakers are anywhere near the wall. You can also take the speakers outside temporarily or in the middle of a very large room to see if that's the problem. If the problem is a bell mode in the port, you might try damping it with putty.

Some common test source signals are sine sweep, stepped sine, log sine (chirp), noise, MLS and TDS. Also note that many systems offer gating for pseudo-anechoic measurements. This allows you to make measurements indoors, because you can configure the system to only sample for a short (gated) period. This prevents reflections from interfering with the measurement, but it also limits measurement of low frequencies. It's great for checking the crossover region though, which is often useful during development.

It's almost like a trick or a practical joke. I like to lay the cabinets on their backs to remove all the screws. Then use a plastic trim tool - like is commonly used by mechanics when removing dash or door trim - to pry up one side of the driver. That protects the wood. Sometimes you can use a bit of cloth underneath the tool to further protect the wood. If you feel brave, leave the cabinet standing but tilted back 20 to 30 degrees. Remove all the screws but one in the bottom. Push the edge of the driver - holding it in position - while removing that last screw. Then slowly reduce pressure holding the driver in, allowing it to slide out.

description: Those look fantastic! I love 'em! Mine are always on foot-tall stands, so I'm with you on the height. I am more than surprised with your comments about muddy bass and unclear vocals though. The four Pi model loudspeaker with JBL 2226H is my reference standard for crisp, clear bass and vocals. I don't think any other loudspeaker performs as well in that regard - If one did, I'd either be back to work redesigning or I'd drop them from the line. My thoughts for suspects are these, in no particular order: 1. Is the cone genuine JBL? Was it purchased brand-new? If not, confirm response and distortion are as published using acoustic measurements. 2. Amplifier performance. How is it doing at 1/10th-watt levels? Most of the time, your speakers will be running under a watt. Then also check the amplifier in the 1-10 watt range. See how it reacts when pushed a little bit. 3. Check your internal wiring. Having one of the midwoofer drivers connected backwards will make some odd nulls in the midbass and midrange, especially when you're centrally seated. It will be off everywhere in the room, to tell the truth. The 2226H is to be connected black to positive, so that's often mistaken. So check the wiring against the plans. Tweeters out of phase with midwoofers won't affect the midbass, but that will affect the overtone region a great deal. 4. Where did you place your insulation? Did you add the sheet spanning the cross-section, between woofer and tweeter? Did you cover the top, side nearest the port and the rear? The rear sheet should almost contact the port. If the sheet spanning the cross-section isn't there, the vocal range will be adversely affected. Actually, missing any of the damping sheets will have an adverse effect, but the cross-section sheet is particularly important. 5. Have you checked the bell modes of the port? Your part looks really cool but since I haven't seen it, I'm inclined to want to check it out. It's probably awesome, but it's an unknown quantity for me. I …

Not visible in the photos is a 1 1/4" x 3/4" MDF rib glued to the top, and a 6"x12" MDF pad glued to the bottom as a platform for the crossover. I used poly batting around the tweeter section and after first audition I also added (4) 12"x12" acoustic foam tiles around each woofer. This made a clear improvement but maybe it needs more damping? Of course I need to do some experimentation with placement in the room. The ceiling has foam acoustic tiles and the floor has a thick jute rug.

Re: Is room treatment a must for bedroom producers?
type: item
description: I've been in a similar situation where I got deceived by my bedroom in terms of sound production. I mean the sound being cool while in the bedroom and sounding a different way while outside. That's why I would say room treatment matters a lot when it comes to getting a good sound quality. It does not mean that you have to spend a lot to achieve that. You can get a couple of acoustic panels that are quite affordable, fixed in some corners, and behind the monitors. That's not comparable to getting new gears, but it can improve the sound quality. I can only say you go for upgrades on the music equipment if you've not got a good monitor or decent headphones. However, if you've got them, then I think doing a simple room treatment is the first step for me.

Re: Is room treatment a must for bedroom producers?

description: It totally depends on the room and what you're lookin' for. The room has a major impact on sound - there's no doubt about that. So if you want to hear the source and not the room, you'll need to do some work. But if you know your room - especially if you're on a budget - and if its flaws aren't glaring, you can probably do a budget setup and be fine. Glaring flaws are things like all hard surfaces like concrete or tile, especially in a small space. That's hard to work with 'cause it will over-emphasize certain sounds and make you want to mix 'em to "correct." Playback in another environment - the sound is way off. One thing that always helps - mount the speakers flush with the front wall and make your listening spot far away from the rear and side walls. If you can't sit far from walls, cover them with acoustic wedges, largest you can get. If you can't mount the speakers flush to the wall, pull 'em away from the front wall and/or use flanking subs.

Is room treatment a must for bedroom producers?
type: item
description: I am trying to know if room treatment should be a major criterion to mix beats in the bedroom. I've done a couple in my bedroom using headphones and a part of monitors, and I always feel satisfied once I am done. However, I don't get the same result if I take the same mixed sound to my car, for example, and I am kinda trying to know if treating the room can have a major impact. I want to know if it does so that I can get some acoustic panels, or is it better I focus on saving up to upgrade the music gears that I use for my bedroom production?

Re: Popular myths about tube amps
type: item
description: Hi. Both an easy and hard question to answer. Any speakers that do not provide specs I would pass on. Ones that do ... for tube use should be relatively high sensitivity. I would want 90 db/w or better. If they give input impedance over the audio band width (unlikely) a more or less linear value would be desirable. They will always have resonance peaks and probably drop off in the high end. If it is excessive then many tube amps will probably have difficulty in that range. Another clue is physical size. If the speaker is small (like less than a cubic foot) and they claim wide response they are likely inefficient. See Theil's equations. Essentially loudness, response and box size are interrelated. That doesn't mean that you need something the size of a fridge although that would be really cool. Specifics. Any of Waynes speakers would work very well on tube amps of modest size. Other than them, most 75 era klipsch, Alted Lansing and similar would be fine. For newer stuff the only ones I am sure of are the Martin Logan ESLs like I have. 20 watts rms is plenty to drive you out of the room. Other ESLs are usually inefficient. Also a what I call a useless spec often given for speakers is max power handling. It really doesn't tell you anything useful. I have seen extreme cases where a 3 inch paper cone speaker was listed as able to handle 1000 watts. It would go incandescent immediately.

The thing is one needs to figure out what works with speakers that they intend using it on before arriving on a conclusion. Making the right decision, just like you said, makes it easier for all. DO you have specific speaker brands that you think can work with solid-state amps, for example? Good to see you back, mate. Wishing you the best of the weekend!

description: I had some nice tweed grille cloth and these speakers being very, well, boxy, it seemed like a good reason to lean into the 'vintage monkey coffin' look. I mocked them up in sketchup, adding a 4" plinth that looked proportional. I have a teenage boy who likes to use my listening room, and while he is pretty careful, his friends are likely to put a hole in my very expensive JBL woofers. So, removable grilles are mandatory. I'd actually like to raise the speakers a bit higher to get them closer to ear level. The plinth might grow to 10-12", but it starts to look pretty chunky. In that case maybe a hardwood stand is more appropriate.

description: Sounds like it's going to be a cool build! You can probably radius the edge of the ports without any ill-effects. There's a formula for calculating the Helmholtz frequency of ports with radiused ends that could be used to see. But then again, that port is huge - in a cabinet tuned and designed for full-range use rather than as a subwoofer. So you won't hear any chuffing no matter how hard you push 'em.

description: 4pi parts are on order JBL 2226/DE250 (and backorder, in the case of the DE250-8's) and in the mean time I'm starting to work out the details. I own a custom cabinet shop with 5x10 CNC router and edgebander, so building boxes is kind of my thing. But doing the engineering of building a speaker is way beyond my mental capacity so I'm glad to have found this design. I've built several kits before including Zaph Audio 5.2 and Adire Audio MTM. I don't want to mess with success so I'll be sticking with the script for the most part. -Would it be a bad idea to fillet the mouth of the port with a 3D printed flare? Or 3DP the entire port with flares at both ends? Presumably sharp outside corners produce turbulence and most ports I've seen have this feature. Would I want to change the length of the port if I do this? -I have 2+ sheets of A1 MDF with a walnut veneer that are very nice and even better, free. I think most folks are using 18mm or thicker baltic birch these days, so I'll plan for more internal bracing. What is the intended enclosure volume? For whatever volume I displace internally I'll need to add to the total enclosure volume, yes? Which outer dimension is preferable to modify? -I'm considering an inset baffle to allow a removable cloth grille panel to set flush. -I will probably integrate a base, maybe some nice hardwood legs and try to make the speaker a bit less boxy looking.

Hi Kurt, I have also heard that myth about SS being better. Nothing could be further from the truth. I have a couple of posts in this string, below, mentioning just a few differences, and why SS will never be perfect to the source but Tube amplifier can be extremely close. One caveat to mention is that as one gets closer to perfect accuracy to the source, one must be more careful to the "little" things. As one example, I have been R&D analog since 1980, delving into audio perception and component design, and use multiple 6N pure copper speaker wires in parallel, for both minimal inductance at high frequencies, and total gauge for optimal woofer damping (at least the best one can obtain). Besides those two, one must consider a flat response over the entire audio band since the speaker impedance changes (usually cone types) from minimal to maximum. I have found that there is an optimal total gauge that will give flattest frequency response, and most natural sound. https://audioroundtable.com/forum/index.php?t=msg&th=21561&start=0& Thanks for starting this string Kurt.
