Differences between woofers
My main speakers in my Tulsa home are three π speakers with Definimax woofers. I spend probably five hours each weekend with them. So I'm starting to get a pretty good feel for them. They sound a lot like the four π speakers with 2226 woofers, to tell...

Re: Pete's Home Theater Build
Sounds like a great plan. I think that's what I would do too.
Are you still planning to run constant directivity cornerhorns? Or are you going back to your original plan of using four π mains? The cornerhorns would be perfect for that room, but one...

Re: Damping H290C horn
Bill Epstein is a big fan of using rope caulk to surround the horn. Some people do that to other horns too, and it sure doesn't hurt anything. If you don't have rope caulk, use modeling clay. Rope caulk is pretty similar stuff.
As for the bass, did...

Re: Uniform Directivity - How important is it?
To offer a little more information, consider the following sonograms:
First, the ideal directivity pattern would be constant through the entire audio band. A constant directivity cornerhorn comes close to this, because the walls confine the beam down...

Re: 4 PI by Andy
Those speakers look fantastic!
But - yeah - I know what you mean about the size of those big-box 10ft3 monster subs. They start getting intrusive when you consider using them in multiples. That's why I designed a smaller cabinet when I started doing...

Re: Subwoofers
I would suggest even more than one subwoofer. Not because they are needed for sound pressure level, but because the smooth room modes. See the attached link for more information:

Re: Pre/pros in THX small in number big in price
I personally could care less about "certification" from THX, because I don't find it relevant. I'm looking for a whole lot more where quality is concerned than what they require for certification. For example, even their highest certification...

Re: flanking subs with small mains
Keep in mind that the flanking sub / helper woofer approach does most of its thing between 80Hz and 200Hz. So if the mains can run to 80Hz, you can run helper woofers like I described and get as much benefit from them as flanking subs that are typically...

Re: flanking subs with small mains
Let me see if I understand you right. This is what I think you are saying:
1. When bass management is used, the sub output is low-passed and the mains are high-passed at the same frequency.
2. You are considering setting this frequency to 60Hz to ...
