Re: Questions about H290C horn and 3Pi Subwoofer
The volume displacement of the H290C is 125 cubic inches sans driver. But the internal volume offsets are taken into account already, so don't "grow" the box to account for internal offsets again. More information about the H290C Horn/Wavegui...

My high school photography instructor was the one that got me into audio. Don't know if he did me a great favor or not but ...
His audio room is particularly boomy. He's been running his system with several subs for a few years ever since he heard wha...

Re: DSP for subwoofer(s)
I've run vinyl for decades, and still do. I always thought it was kind of fun to crank up the speakers and watch the cones move at VLF where they are unloaded in vented cabs. Long before the days of computer modeling programs, I noticed some (too small...

Re: Are subwoofers worth it?
So, if I'm understanding correctly, if my budget could allow me to get one really great subwoofer or two pretty good subwoofers, you think I opt for the two instead of the one? Do you think it would be wiser to just save up some more for multiple highe...

Re: 7pi plan and guidance request
That room will work very well with constant directivity cornerhorns.
The seven π constant directivity cornerhorn generates 101dB/W/M and is capable of over 120dB/M at full output.
I would put the seven π cornerhorns along the 15-foot wall, just as ...

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: 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: 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.
