I have the 10B-STD. My system is very transparent and I didn't notice any degradation in sound after installing. If there was any it was far outweighed by the improvements that came from properly crossing over my subs.
Having the flexibility to set cut over frequency, level, and slope independently for each channel is is a nice feature. this helped in my case because one sub is in the corner and the other is not.
