I take it by out of phase, you are electronically going 180 degrees out of phase to produce the null at 90 degrees? I've designed antenna's based on this principle (dipole with nulling at 90 degrees off axis), and that sounds sort of like what you have done. To accomplish it, are you just wiring the drivers in reverse on the "pull side"? I see that a lot on foreground audio 2 way speakers between the woofer and tweeter, but I've never thought of doing it on this scale before, though.
The 90 degrees he is referring to is physically 90 degrees from what I would call the front of the enclosure. But yeah, the drivers are electrically 180 degrees out of phase. . .
I'll take 4 of them for each corner of my living room and facing them towards me, and I'll take 4 of those pyramid mid-range speakers. With of course my Samsung 46" LCD TV in the center of all that. lol
In monopole it's just another subwoofer but in dipole the bass becomes directional. Essentially you could have lots of bass and neighbors wouldn't be bothered. In a real fast dirty explanation that's it.
lol but either way your neighbours would hear it feel it dont forget sound bounces so really its just not worth it ? why you fink we usually place subs in the corners or near them
Wow, I don't see the need for this. I rather use a normal subwoofer. :p

so what is the purpose of this sub ? where would you use it why would you use it instead of a normal sub

Controlled Directional Cancellation. Very nice.

so why not wire all the drivers in phase and.. shake your whole house!

thats funny, we first did that and broke a wall, literally cracked the drywall.
