Summary:
I found the SB-4 to be very power hungry. I just picked up a Parasound HCA-2205 and thats when my Ohm SAT's and the SB-4 really came to life. The SB4 has the low end of the Walsh 5 (L/R front). I was always impressed with the Ohm product,but never fed them with enough power. I fell in love again. As far as I know the SB4 is the only sub with 4 inputs(voice coils),very flexable.I use two of the inputs on the SB4 for L/R rear with two Ohm Sat-2's. I use one of the inputs as my sub and change between the Walsh 5's(center off) and a Sat-2(center) wired thru the fourth input. With enough power the SB-4 will not leave you with powered sub envy.
Great sub (give it the power it needs)
