Thinking of a SVS 25-31 Cyl series and was not sure if my receiver (Denon 1801 70wpc) would be able to power this sub. Or am I way off base because it looks like the powered version comes w/a 320w BASH amp. And could you make any recos on a smaller sub that handles the lows well. I live in a apt so extremely high volume is not a huge issue. I am running Axiom M22s and a VP150 as the remainder of my system. Running a Sony Wamb40(think that the model #) and it is not doing the job. Was great as a hold me over but now I am much more critical of the sub. Also want to keep it under $400 is that possible? Thanks!
