Artmaltman,
I've had great success with the Velodyne SPLR 1000s (2 in the LR 2 channel / HT) and also the newer REL R series (3 in different systems).
Although a bit pricey, the RELs are simply fantastic with music and are very fast and mate well with just about any speaker and especially so with a quick single driver speaker. The Velos are no slouch either and, while they have different modes (Rock & Pop / Games / HT / Jazz), for music I always run them in Jazz mode. This keeps things nice and tight with no flab or exaggeration whatsoever.
Cheers,
Garry
