If I were to go with a system geared more to music, I'd like the VTF2--although it is no slouch for HT. Remember, this is just my opinion, but I slightly preferred the sound of the 10" driver with music. Also, this was the Mk2 version of the VTF2. The current VTF2, designated Mk3, uses a 12" driver.
I was looking for maximum slam for HT and ended up going with the VTF3 Mk2. I really hesitate to tell you which one to get because it's really subjective. Both subs sounded great. For a music only system I would have chosen the 10". As it was, I needed one for HT as well, and wanted something big and powerful and went with the 12".
I haven't heard the newer Hsu subs. My advice for subs is to buy the biggest you can afford. As long as you keep the gain under control it won't overpower a small room, and you're future-proofed if you move into a larger space.
