Hello there, my name is cris and i am a new member from Greece! I Just bought the Monitor Audio RS W12 Subwoofer which replaced my Yamaha YST SW 320! I am quite satisfied and i think it's a great sub! I was between the following Subs: 1.Velodyne CH 12R 2.B&W 610 and the Monitor Audio that i prefered! Does anyone have it? What's his impressions? My rest of the speakers are the following: Front:Roister Silk 100 (which i will replace them with the B&W 603 S3 that my father has) Surround:Roister Status Center: Kef Model 100 My AV Amplifier is an old Sony (Str DB 840 QS) that still satisfies me! I am mostly watching Films (80%) and Music (20%) After having it about 15 days now and working on low levels because it is still new , from yesterday i started giving it more power! It Really Kicks!!! I have connected it with a double rca cable (left,right) because my Amplifier has double Lfe OutPut! Am i Right? Also I keep the volume a bit less than the middle! Like 10 o'clock (about 40%) Thanks!
