So ya I went down to BB and heard the Def 350's, ya the sound is amazing but just not as low as I want, I was thinking of adding a sub to them, had it all plained out and what happens, the BB salesman with his stupid mic comes in, whats even worse IMO I knew how to work the switcher better than he did, pah! Then is trying to sell me a set of def sat speakers its like DUDE what was the first thing I said to you. NO SAT SPEAKERS!!!! JEEEZ after taking me out on the floor and trying to convience me on some polk SATS I was like forget it bud im gone, aside from this guy treating me like a complete moron their is a good thing about the whole thing, i prevented BB from making a $1k bucks of some guys hard earned money on set of yammy's and dennons that were EXTEREMLY over priced for older receiver, and steered the guy on to this website and the whole world of speakers, as soon as the salesmen came in that guy bailed. Audioholics.com-1more, BB-0.
thanks for the help though i will be buying those speakers and using my yamaha rx-v663 receiver.
