Check the NHT subwoofer close-outs.I bought the A1/X1/W1 system for my HT set-up.It is a very good subwoofer system.My friend bought the same set-up with the single woofer sub enclosures for his bass augmentation ,under the Merlin mxe.He complained a little about the transparency,but this shouldn't be an issue in a HT set-up (.1).He changed the crossover out to an LP-1 and is extremely happy.
The benefit of the X-1/2 crossover in a HT set-up is that there are a myriad of controls at your disposal:X-over freq,phase and boundary control.It also allows for use of two subs and additional routing for a summed/single unit.
