Ok I have read all the discussions about mono vs dipole vs bipole. I am still confused. My new room is 12 by 18. I plan on having my current direct radiators (pinnancles) in the front, center, and rear center. I wanted to put bi or di poles on the rear sides. Or quasi dipoles that have the highs out of phase but the lows in phase. First which one. Bi, DI or quasi? What brands would match my current setup or are best sounding? I have auditioned PSB Atlantic and Def Tech. Unfortunately all have been in different settings. So far I felt that the PSB's were the fullest sounding but again this test was limited because the material was different and the location. The use will be primarily for movies.
