I recently inherited a HSU VTF-2 MK2 sub and i'm wondering how well it stacks up in terms of musical reproduction. I listen mainly to classical, jazz, and indie rock and i'm much more concerned with the ability to reproduce bass notes cleanly and quickly without distortion, booming, sloppiness, and all those other nasty pitfalls that have come to characterize so many larger HT-oriented subs.

I've done some research, and, from what i can gather, a sealed sub is what i'd ideally be looking for considering the more gradual low-extension drop off. The obvious compromise to a sealed setup would be maximum output, though thats not a priority for me.

Fortunately, despite high praise among the HT community, the VTF-2 also has a max-extension mode allowing one of the two ports to be plugged, thereby effectively lowering the frequency response to ~25hz, which makes me happy. How well does this work? Is a "hybrid" setup like this recommendable?

And more specifically, has anyone bought a HSU sub for incorporation with a setup build chiefly for music? If so, how do you like it?

I hear a lot of good things about the Martin Logan Dynamo - maybe i'd be better off trying to pawn the VTF-2 on ebay as it's in flawless shape - it basically sat in the box for two years. Decisions...

Any and all suggestions/info would be greatly appreciated.
