I another Forum Garmtz said:- I thought I'd reply to this part in the "Speakers/Subs" forum as I may end up taking the thread off topic otherwise.... I'm currently using an M&K V75 Mark II Sub which I find fantastic in my current room. It's obvious to me it won't suit my new room. I recently bought a B&W THX set that contained 2 X PCM8 Passive THX subs. My thoughts were to use these, powered with my Denon POA-T10 for my very much larger new room. I'm currently EBaying the FCM8's THX monitors that came with them. Do you think I'd be better off Ebaying the PCM8's as well and buying passive subs (Servo 15's?) instead? The new room is a MASSIVE 42ft X 20ft (13M X 6M) X 2 storeys high. Mark.
