Your NHT "Super" loudspeakers are not only a great buy, but truly excellent sounding--especially the much-heralded Super Zero. I owned a pair of Super Zeros for nine years--I only recently replaced them with Triangle Titus 202's.
My suggestion may sound a bit odd at first, but I bet you'll like the results:
Make the Super Zeros your two main front speakers. Use bass management on the Denon AVR to route both the sub-80Hz bass frequencies and the LFE channel to the SW2pi. Now, move the Super Two's to the rear surround location.
I'm not kidding--try it out for kicks and I bet you'll like it. The Super Zeros are just too darn good to be relegated for surround--and would provide truly seamless sound with the Super Center.
