Re: Multiple Subwoofers
Multiple subs are the only way to go in my opinion. It's done more to smooth out room modes than to increase SPL. The idea is to place them around the room in different places so self-interference that is destructive from one sub is filled in by anothe...

JBL 2226 Usage
I meant to say this earlier, but then got busy with my morning things and just clicked "send". I wonder if what you're hearing (or missing) at low levels is a Fletcher-Munson thing. I could understand that, 'cause the deep bass needs more vol...

Information about π Speakers
I like the six π or seven π constant directivity cornerhorn speakers if the room has the right corners, or the three π or four π matched-directivity speakers if not. The eight π loudspeaker is sort of a budget hybrid model that also provides uniform dir...

Room Treatments
Those panel traps are probably the best thing you can do to tame room modes. You can't hurt yourself putting them on every wall. If you're lucky, framed drywall will come close, but even then, the extra damping won't hurt. They really help rooms with ...

Re: 1-Pi/2-Pi
I don't build transmission lines, as I've always used Helmholtz resonance to tune the box instead of pipe modes. I designed the box with standard Helmholtz resonance formulas and then used Martin King's spreadsheets to verify that port and driver plac...

Re: 4 Pi and 7 Pi bass response- More similar or different?
Yes, you could do that. If the false wall is large enough it will work pretty well. My concern is it might be awkward, but maybe not. If it does prove awkward, you can always stick with four π speakers.
You might try adding the midhorn on top...

Re: 4 Pi and 7 Pi bass response- More similar or different?
To me, they definitely sound more alike than different. All my speakers have basically the same tonal balance, and they're all designed to generate a uniform pattern. They all use the same tweeters and woofers, at least in "families" - three ...

Re: Going without a subwoofer.... even with smaller drivers?
I only scanned through his approach, so I may have missed some detail. But in general, I think he's using an overdamped vented alignment, one that gives a gradual rolloff, much like a sealed alignment. I'm cool with that, it's a very forgiving alignmen...

Re: enclosure uni project, and ideas?
I would suggest four things:
1. Contact Martin King and see about getting his TL modeling software. He can be reached at www.quarter-wave.com.
2. Setup and learn acoustic measurement equipment, if you have not already done so. There are several...

Multisubs
Next step then (in my opinion) is to getcha some subs. I love the sound of my four π speakers even without subs, but adding them puts them really over the top. It's really about smoothing the response as much as it is about increasing extension.
