ezkcdude, I think you made the right choise w/the VTF-1.
The VTF-1 is very similar to the original box sub from HSU,
the VTF-2. Same spec's, except the VTF-2 had a 150w amp,
and the present VTF-1 has a 200w amp.
I've owned two VTF-2's (would of bought a VTF-3, but it was
unavailable back then). I've also have two Dayton 10" Titanic
MKIII subs, which I use in a second (smaller) home theater.
They are good sub(s), but the VTF-1 will dig down to 25HZ
(max extention) and 32HZ (max output).
The Dayton Titanic subs are great for the money. But the 10"
will go down to 30HZ and that's about it. Pretty musical though.
If the amp in your Dayton 10" sub is bad you can replace it
from ordering it from Parts Express for about $100 w/ $50 off
or if it's the driver:http://www.partsexpress.com/pe/pshow...number=295-414
But I think you made the right decision with ordering the VTF-1,
