dual caps for the $3600 range. they'll likely be the most powerful capable subs you've ever heard anywhere...
duals of any of the other JTR or Seaton options will cost you quite a bit more than your stated budget. I prefer duals. It isn't necessary, but it is preferable depending on your room. I have a 3500 cubic foot room and I've played with Luke's VTF-15H pair in my room. I'm a bass hound, so take that into context, but I didn't feel the HSU subs were sufficient for my likes in my room. By contrast I LOVE the dual HSU subs in Luke's 1500 cubic foot room. It depends on what you like. If you owned a car audio system growing up (or still do
) and you want to obtain a taste of that kind of bass pressurization in your room you're going to need a lot of sub to do it. How much sub you need depends on your room size. If you don't care about that - then you don't need this much sub. Consider that the likes of these top subs are better quality subs than what is typically used in mega churches, auditoriums, dance clubs, etc. These things are serious business.
What is your room size?
Also keep in mind that like Audiophile2k says - TV broadcasting isn't going to showcase the lows as well as bluray or DVD. In reality as setup like the caps are vast overkill for 99% of the population out there. My advice in purchasing them is somewhat ridiculous and glorious overkill.
That said I love my pair and I believe they are my favorite single purchase I've ever made through my whole life --- even 1 year after my purchase timeframe. You may find you'd be perfectly happy with incredibly less sub. I personally wanted to somewhate imitate the tactile feelings of car audio in my theater room - that isn't for everyone. If you just want to hear the bass primarily for TV - then you could probably buy a set of something like the Klipsch RW-12Ds that are currently on sale for $300 a pop and be perfectly satisified. Lots of people are. That wasn't your budget, so we didn't start there, but you need to help us determine what your expectations are --- along with your room dimmensions.Edited by Archaea - 8/12/12 at 8:19am
