Thanks to everyone for their help. It gave me a lot of different options to think about.
Last night I picked up a sub - which did solve the problem but only for home theater. It turns out (and I should've known this going into it) that my B&K Reference 10's bass management only works well for digital sources; if you turn it on for an analog source it sounds like it's digitizing the signal, crossing it over digitally, and spitting it back out again.
In other words, it sounds awful.
So - I'm returning the sub. Many people suggested them, and the store I frequent has a pair of floor-sample PSB Image T-45's - so I'm going to give those a try.
Thanks again everyone.
