Re: Information about the 3 Pi Subwoofer
…for smaller rooms - those that need multisubs even more than larger rooms do. But a smaller box would need to be less efficient.
I chose a vented alignment because I think vented cabinets are the best direct radiating configuration. I really only …

Re: Tuning below Fs with JBL 2226H?
…to use a multisub configuration. It is done to smooth the sound field at low frequencies by making sound in the modal region act more like the statistical region. For more information, see the link below:

… in multiples. But for me, 4ft3 subwoofers aren't too large. I run a pair of them flanking the mains, and another pair behind the seating area, and this gives incredibly smooth bass response throughout the room.

Re: Flanking Subs vs Helper Woofers
…when both flanking subs and distributed multisubs are used, with the distributed subs running a summed LF signal, and the flanking subs running the same (low-passed) signal as the mains they are flanking. Some people use just one distributed (summed) …

Re: Flanking Subs vs Helper Woofers
I can see how this works with stereo. But it's not as clear to me when it comes to multi channel audio where the LF content from at least 3 more discrete channels and LFE are all summed in the subwoofer signal.

Re: Flanking Subs vs Helper Woofers

Re: 3pi, smaller cab possible?

On the other hand, if the dimension changes are large enough, then the directivity changes will become apparent. Narrow baffles cause directivity shifts above the modal range, up in…
