Re: Helper Woofer Location

Re: 4pi Commercial Dinner Theater Build
Answers by numbers:
1. If I understood your picture properly, the west wall is on the left, where the mains are. So that would be where you would put flanking subs. Distant subs would be put somewhere else, more distant from the mains. The low-pas...

Re: Information about Pi Speakers
What you want for flanking subs are sound sources that are smooth through 200Hz or so. Pretty much any direct radiating sub will do that just fine, regardless of size. Most subs will, to be honest. The only thing I'd stay away from are tapped horns, w...

I wouldn't do a sealed version of the four π loudspeaker, except for one application. The center channel of a home theater system having four π speakers can be made sealed, with the left and right being standard models, mirror imaged as usual. In this ...

Re: Sub woofer Assist
Check out the thread called "The Subwoofer Thing" along with all the links contained therein. It's about a configuration that uses multiple bass sound sources at different places in the room to average out room modes. Some call this a multisu...

Re: Sub crossovers
Now there's a pair for you!
Seriously, that will work just fine.
I used the Rekkhorn F1 sub crossover, and it worked pretty well. It allows variable adjustment of the (24dB/octave) low-pass frequency and amplitude. But honestly, I kind of like ...
