Thanks To All...
First off, thanks for all the input, folks. This type of feedback was exactly what I was looking for. As I didn't have my heart set on any one of these in particular, it was great to get as much input as possible on all the subs I mentioned and then some...
Well, it'll be a week or two, but I think I'm going to have to go w/the Athena AS-4000 for this. At ~$150.00, this seems to be the best "bang for the buck" in this application.
I would definitely consider the ULW or the STF-1/LFM-2 if it were w/in $100.00, but closest I can find either of these is near the $300.00 range. Weighing the difference in price for performance, I just don't think these other subs would be worth the jump in price. -TD
