I have Monitor Audio Silver S10 fronts and a SLCR center. I couldn't decide between the QS8 or the MA SFX surrounds so I picked up a a pair of the QS8 and SFX to compare against each other. The SFX goes down to 60hz +/-3db, so setting the crossover is easy, but the QS8 only goes down to 90hz+/-3db and then trails off -9 dbs(which is a lot) down to 65hz.

Since the QS8 has usuable sound at the +/-3 db at 90hz how do you integrate a 80hz or lower crosover without having a whole in your frequency range?

Thanks
