I upgraded my av system over Christmas to Marantz SR6003 paired with Monitor Audio RS6, RSLCR, RSFX's and have been very happy with the sound. The visuals are provided by either an Hitachi 9700 plasma or Sanyo Z2000 throwing onto a 92" screen with the PS3 and Sky HD as the source. Now my mind is turning to subwoofers and my initial thoughts were to go with the matching RSW12 (can get for £600ish). However, I am not sure if that is the best option at that price. The room is 18ft x 12ft and I would struggle (without a serious rearrangement) to get in anything with a much larger footprint. I have checked out Index to Subwoofer Tests by Manufacturer/Model - DVD Plaza Forums for the response curves of different models but they do not list the RSW12 (only the BRW10). I reckon that the mix is 70% TV/Movies/Gaming and 30% music. The only wife friendly criteria is that is must produce a good quality sound (?!?!) and be black! Any suggestions?
