This is my first time posting so sorry if I'm in the wrong spot.
I want to add subwoofers (2) to my system which is currently FL, FR Yamaha NS-1000Ms driven by a Bryston 4B-ST and C is a B&W SE CDM something (pre-Nautilus) passively biamped by a Sonograph SA 250. I'm considering putting the NS-1000Ms on top of the two yet-to-be-purchased sub cabinents.
I recently bought a Crown PSA-2 with balanced inputs and had it checked out by a pro audio repair shop. I want to use the PSA-2 to drive non-powered (obviously) subs. The NS-1000Ms go down to 40Hz according to specs. I have several ASC TubeTraps of varying sizes but going as low as a Super 16.
Initially, I plan to drive both subs with one Crown PSA-2 but will pick of a second PSA-2 and bridge both if I don't find the fan noise distracting.
What do you folks recommend for subs?
