Re: Corners and frequencies
I've designed constant directivity cornerhorns for over three decades, and the current configuration is the best I've come up with. There are a handful of competing priorities, some that you've mentioned like listener height and others too, like acousti...

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...

Re: Looking for a change
I've sent the plans. You've got mail!
I would suggest using your existing subs, flanking the mains, as described in these posts:

Re: 4 Pi and 7 Pi bass response- More similar or different?
A constant directivity cornerhorn doesn't suffer self-interference anomalies from nearest boundaries. So there is no need for flanking subs. Instead, you would want to setup the subwoofers as distributed subs, a little further from the mains and low-pa...

Re: 4Pi Placement
The main thing is to cross the mains axes in front of the listeners, and to use flanking subs. The flanking subs will both add extension and also smooth the self-interference notches from the wall behind the speakers, vertical modes and other similar an...

Re: First coil in woofer's LPF with and without helper woofers
That's kind of the point, yes. If you don't use helper woofers, then the mains are the only sound sources down low. And those tend to both rolloff sooner and shift source directivity from (baffle influenced) halfspace to omnidirectional. Then add to t...

Re: "Are Audiophiles Wasting Their Money?"
Hi, I have encountered a number of similar thought, both pro and con. I find there is some merit to each. If you go the really cheap route and get big box store stuff it is almost always unsatisfactory in some manner. Frequently it will not last well. ...

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
Yes, I expect self-interference and room modes are likely the problem. I use the three π subs, which have a LAB12 woofer in them. But you can use a smaller sub, perhaps one that doesn't give as much extension, if you're worried about bothering the neig...
