Re: Might this be a quadrupole?

Greater sound pressure with more cone movement/area? I don't understand the benefit either.

Then again, I am confused by the need to move speakers several feet out from the wall to avoid 'bad' reflections, and the relatively new fad of putting drivers in the back to created reflected sound.

My 4JRs do this with a tweeter, and I do like the enveloping affect. I have recently seen large mid/woofers taking the same approach. Is this the next evolution of that?
