Sub Suggestions

Doesn't Aerial make a sub? They'd likely match your Aerial speakers.

A single Aerial sw 12 sub could be all you need . Two is better of course as each could be used for seperating bass for each channel but the unit has a switch for summing the input. It also has a switch for movie and music and you can optimize the sub for both. Other than that , the SW 12 is a fantastic sub and would mate nicely with your speakers. Beautiful , near indestructible and harmonically rich ; music reproduction for this unit has few peers. For theatre , it is very good to excellent.

velodyne spl 1200r's sound pretty amazing!

I think the Rockets have a parametric EQ on board also, yes? Not sure on that, but think so. That would help as well

I want something smaller than the Aerial SW12 and I don't want to spend that much given that it would only be used for HT and sit there 98% of the time doing nothing. I like 2 channel music most, everyone else wants surround sound. But know that this mode will be rarely used for the most part.
