Hi folks. After much research I am finally putting together my home theater. I will be using B&W FPM 4's for the center and surrounds (this is a concession to the wife) and I'm wondering if it is important to use a B&W sub as well. My instinct is that it's not. It seems to me I can get a very good SVS or Outlaw sub for less than a perhaps poorer B&W sub(under $1,000). Other than needing some more time/effort to find the correct crossover frequency on an unmatched sub, are there any other issues or considerations I need to be aware of? The B&W sub that has been recommended for the FPM 4's and my room size is the ASW 675($899). Has anyone heard this sub? Does anyone have any recommendations between SVS, Outlaw and B&W? The system will be used for viewing movies and television, listening to music and playing video games - your basic all-purpose home theater Sorry for the barrage of questions. Any input would be greatly appreciated. Thanks!
