A subwoofer and sub-controller (like the Velodyne SMS) is one viable solution. The SMS is +/- $400, and if you have 2 pre-outs (or an active x-over like the NHT X-2 @ app $300),you can keep the EQ unit out of the main signal path. It will work in the main path, but it uses ADC prior to room correction/EQ, so, given your stated preference, I suspect that you'd be happier isolating it.
Digitally room corrected subs are a wonderful thing! One more nice benefit - multiple presets. You can store full , room corrected bass response under one preset and polite, rolled off, neighbor-sensitive bass response in another. Switch in the bass when the neighbors are out, play nice when they're at home.
However, you need a sub/main speaker set-up to make it work.
OTOH, I lived on the 32nd floor 60 E. 8th st for 16 years and I never found a truly good solution.
Good Luck,
Marty
