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: The subwoofer volume and crossover
I was generalizing the concepts and using "round numbers" in my earlier post above.
Flanking subs are setup to blend generally in the 100-200Hz region, but in practice the blending region is shifted a little lower than that. Distributed mul...

Re: Why is drywall bad?
That's true. Rooms with framed drywall construction are much better than rooms with brick, stucco, concrete or rock walls. The drywall panels vibrate enough that they absorb some of the bass frequencies, and so act a little bit like panel absorbers.

Re: Small-room acoustics
Actually, small rooms are harder to work with than larger rooms. The reflections and room modes are more intense in a small room. Speakers that can provide uniform directivity help reduce problems in the reverberent field, above around 200Hz, and as yo...

Re: The subwoofer volume and crossover
The answer to that can range from simple to complex. So let's start with simple, move towards more complex topics and then leave it to those interested to research further.

Re: Placement of the speakers
Left and right mains should flank the video screen, and be at the same vertical height as the screen. The center channel should be centered and at the same height as the screen. That's only possible of the screen is acoustically transparent, so some pe...

Re: What is the best way to get better bass in my home system?
I agree with Bruce with respect to the quality metrics of an individual subwoofer.
I'd like to also bring to your attention the concept of multiple subwoofers. I believe that is the most effective thing you can do to achieve good bass response in you...

Re: The bass levels
Wow! This basically sums up everything I have been putting my mind to task on. I think I will just have to get multiple subwoofers for that matter since I've never been able to fully optimize the sound in my room.

Re: The bass levels
Equalizing the bass is not the best way to solve the problem. The best way is to use multiple subwoofers. The reason is bass problems are almost always caused by room modes, not by the subwoofers. Room modes are caused by self-interence, interactions ...
