Re: Helper Woofer Location
The best approach for the helper woofer is to locate it physically between the main midwoofer and the nearest room boundaries. So you might want to put the helper woofer on the back, near the bottom. I sometimes call this a "flanking sub" app...

Re: 6 Pi
As you know, the response of the three π loudspeaker is very smooth and distortion is low. But so is the six π cornerhorn, and it has the advantage of true constant directivity, with reflection-free wavefront propogation. That's a real big deal. One...

Re: LAB12
The crossover to the sub depends almost entirely on the distance from the main speaker(s). The further away, the lower crossover needs to be made. I think a good rule of thumb for indoors use is to crossover around 1/3λ. Outdoors you want to bring this d...

Re: Speaker placement and wavefront launch
I have two answers for you, one that you asked for and the other, you didn't. First is the reason sound waves become spherical at a distance. All sound waves in free space tend to radiate this way, even if they start off as a plane wave (like from ...

Re: Speaker placement and wavefront launch
The illustrations show radiation from a monopole source with boundary distances relative to wavelength. You're right that different frequencies create different patterns in the room, because the speaker is a fixed distance from the boundaries. But thes...

Re: 4pi Commercial Dinner Theater Build
Flanking subs and distant subs are two different things, and serve two different purposes. Both provide extension, and beyond that, the main purpose of the flanking subs is to smooth the upper midbass and lower midrange and the main purpose of the dista...

Re: 4pi Commercial Dinner Theater Build
I think they will work well that way, just be sure to delay the mains to match the path length of the subs. Orient the subs with the mouth near the floor. If the F20s sound good in the ~120Hz range, I'd low-pass them with a shallow filter slope, like...

Re: Grills for your 4pi? 1pi?
I like to avoid grilles when I can, because they create a reflection that makes self-interference and response ripple. That said, sometimes they're a necessary evil. I have a 4-year-old, so I'm running grilles right now. For home hifi, I like to...

Re: Speaker Screens
Anything in front of the speaker will act as a reflector, and will cause self-intereference, which in turn, will cause ripples in response. The more acoustically transparent, the better it is (less ripple as well as less loss). But even the most acoust...

Re: 3 Pi Subwoofer Plans
Sounds like you've thought of most things, so I think you're on the right track. With the cabinet baffle mounted flush to the wall, you'll have no self-interference from that wall. And keeping driver spacing the same (in all three dimensions) will get ...
