On saturday, I visited a local stereo store that handles B&W and Definitive Technology. My intended purpose was to listen to the B&W 604S2 and to decide whether a 601 or 602 would be the best rear channel. I addition to the B&W line, I was also looking at Paradigm (Studio line) and Boston Acoustics. My home theater room is approx 20x20 and I have only 50% of a rear wall. One side of what would be a rear wall in an ideal setup opens into an adjacent room with a pool table. Because of this, I've been thinking that the rears should be direct radiating versus one of the effects speakers that fires to the rear. Without a rear wall, I was concerned that the intended reflection from one of the two speakers would not occur and the sound would be screwed up. Also, from reading this forum it sounds like many of you have selected direct radiators for rear surrounds in 6.1 systems. The salesman suggested I compare the B&W's to Definitive Technology (huge 2000 front right/left with integral subwoofers). First, he played a movie soundtrack. I gotta say, the Definitive speakers rocked and definitely had more impact and did a better job than the B&W's. The 604's were mated to a subwoofer that cost approx 800 (i dont remember the name/model). Next, we played some music. Here, the B&W's really shined. They were much smoother and easier to listen to. In comparison, the Definitive Technology seemed very harsh. Since I will be listening to both movies and music, I came away preferring the B&W's. Even though the B&W was not as impressive with home theater, I felt it was a more accurate and musical speaker. For rears, the salesman recommend the 601 due to my room configuration. He felt that the dipole/bipole speakers would not work well due to the half-wall at the rear. Unfortunately, the 601's were not setup as rears in the room with the 604's and I could not compare directly. I came away thinking that the 604's with 601's was looking like the setup for me. Over my lunch hour today, I visited a speaker store close to work that sells Monitor Audio. I had never heard of this name, and was mostly interested in finding out if he agreed with the assessment that direct radiators were best in the rear. This particular salesman has a great reputation for knowing his stuff. Wouldn't you figure, he disagreed and recommended a rear set (made by monitor audio) that can be switched between dipole and bipole. He did not feel that the half-wall would be a problem. Note that he sells a Monitor Audio direct radiator that would compete with the B&W 601. To make matters more confusing, the Monitor Audio speakers I listened to (Silver 5i, Silver Center 10i and Silver FXi with a matched subwoofer) sounded great. Given several days had passed, it was hard for me to compare with the B&W's (which also sounded great on Saturday). I've never heard of Monitor Audio. Do any of you have experience with this manufacturer? How is it generally felt to compare with the B&W 604's? Or the Paradigm Studio speakers? What about the rear effect speakers. I know a lot of you have direct radiators versus bipole or dipole. Why did you choose a direct radiator? Based upon the guy I spoke with today, a good bipole/dipole rear effect is far superior to any direct radiator of similar size. Once again, I'm confused and am getting headaches about this decision. My wife thinks i'm off the edge. Any help would be greatly appreciated.
