Re: Horn mouth vs. front baffle or "speaker cone"
I definitely understand what you've described. Geddes suggests placing one sub high in the air like that, specifically to deal with modal smoothing in the vertical dimension.
My guess is your troublesome mode is probably in the 60-80Hz range. Partly...

Re: Two Subwoofers
Outside and inside are very different.
Outside, you want all sources to combine coherently. This means you want sound sources grouped together, and their acoustic centers aligned.
When two subs are placed at each ends of a stage, bass suffers from...

Re: Subwoofer Setup
That's great to hear, Barry. Thanks for the feedback!
As you and I have discussed, I'm a big proponent of multisubs but I consider the flanking sub aspect to be an additional requirement. I think that distributed multisubs by themselves only solve p...

Re: DSP for subwoofer(s)
You're right - the main thing is number and placement of subs.
I understand that you want to use a DSP crossover because it gives you the ability to choose any crossover point and slope you want, so will be easy to set the requisite ~90Hz second-order...

Re: Are subwoofers worth it?
If you can tell the subs are on, you don't have 'em setup right.
I used to prefer systems without subs until Todd Welti introduced the multisub concept in the early 2000s. I expanded upon it to include the concept of flanking subs. Both approaches s...

Re: 7pi plan and guidance request
If you have the right corners, I would suggest using the 2226 drivers in seven π constant directivity cornerhorns and make subwoofers from the 2242 drivers. Put the subs in opposite corners or somewhere distant from the cornerhorns, in a multisub config...

Re: How many subwoofers
More is better. Place them around the room to smooth room modes.
Going from one to two makes a huge difference. If you have two, I suggest making them flanking subs. Two to three makes a big difference in smoothness too, especially in the deepest b...

Re: Mono "flanking sub"
Physical position of midrange and tweeter drivers is sometimes offset to get the summing right. It's kind of similar, except in this case, the goal is to match the phase of each subsystem.
In multisub setups - both flanking and distributed - we're ac...

The most optimal placement for a single sub
Hey Wayne! How are you liking Arkansas?
I'm still planning on getting a stereo pair of 4 Pi speakers, plus a pair of 2 pi speakers.
I'm torn about what to do about bass. I like the multisub idea in theory, but it would be nice to have one mega ...

Re: Two 3 pi subs to replace my horn?
You've got mail!
Hornsubs are about 10dB louder than most direct radiating subs, sometimes even more. So it takes more power to get the same SPL, and even then, you really need more of them to prevent overtaxing them.
On the other hand, hornsubs h...
