Bi-Polar.... Di-polar.... Whatever.... Fact is, you CANNOT get a true Bi or Di polar effect from an In-Wall speaker. Its a joke that they call the In-walls bipolar.... Smoke and Mirros...

[Link: audiovideo101.com]Not to say they dont sound good... I think they sound fine. Very good even...... but they are NOT bi-polar.
One of my favorite speakers I ever owned were Mirage 3Si's.
Spectacular sound in the right room..... Unfortunatly I dont have the room for them anymore.
