Matching Sub for NHT SuperZero XUs?

I have a 5.1 set-up with 5 NHT SuperZero XUs as the front, rear, and center spkrs. I am entertaining the purchase of an SVS PB10 sbwfr to complement for both audio and home theater. Does anyone know how this sub sounds with the NHTs? I know the crossover has to be set pretty high w/ the NHTs (one recommendation was 120 Hz- any others?) Reviews of the SVS PB10 seem to indicate it's best in class, price-performance and that it sounds great with other existing spkrs. Anyone have a SVS/NHT setup? Any other sub recommendations? Thanks.
