Re: Definimax 4012HO - End of Life
I'm not ready to make an announcement, but I can give a status update. I have a pair of Eminence Delta Pro 12A woofers and a pair of B&C 12PLB100 woofers here to test with. Both look like they will work very well from modeling and from free-air...

More on subs
A friend has a really troublesome room. Nice gear but tough room. We've implemented multiple subs in three steps in the past year or so. I'll spare you the details of why it took so long to bring it all together as there were a few technical obstacles...

Re: Amp for 4pi speakers
Nice to read that I (and the room) did things right there. I guess my expectations were wrong here. Should have read your paper better. Can I get good EQ with 200$ budget for EQ? If so, any advise? Any thoughts about MiniDSP 2x4? ...

Subwoofer Setup
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...

7pi speaker parts and multiple subs
Hi Wayne, A couple of years ago I stumbled on your designs and you kindly sent me the plans for the 7pi corner horn when I suggested my lounge might be ok as a suitable location. I am in the UK so it has been necessary (cost wise) to collect parts loca...

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: 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: Mono "flanking sub"
When we talk about phase anomalies (time domain) or when we talk about peaks and dips in the amplitude response (frequency domain), we're essentially talking about flip sides of the same coin. I've always been more focused on the frequency domain becaus...
