Subwoofer choices under 1K . NHT, Def, SVS


Making a plunge into HT, but probably will use my system 50% for music.

Need help with a sub selection..any ideas welcome

I have a big den, over 3000 cubic ft, with NHT 1.5's as the fronts (AC-1 center). Got em on closeout, great but no bass.

Choices:

* NHT SubTwo (b-stock or closeout)....est 700
* SVS (probably the 25-31)....550
* Def Tech's Supercube 1 (pricey)...1100K.

I'm sure there are other choices out there, but wanted to get input. I want decent HT performance, music isn't the only use, but I don't want boom-boom-boom.

Boston PV1000 lists for $1200, but can be easily bought under $1k. A real Velodyne HGS-clone for 1/2 price! And BEAUTIFUL, too.
Go to acoustic-visions.com.Adire makes a driver called the "Tumult".I bought two because firt off I'm the biggest sceptic in the world and second I had two seperate killer enclosures on hand for a project.Adds can say what they want but when you plunk down the bucks I want bass.I installed one 15" inch driver in a 2.5 cu. ft. sealed enclosure and the other 15" in another sealed enclosure.Stuffed them with some owens-corning and screwed them in hoping for the best.Fed them with a pair of bridged mono Adcom GFA 555mkII's ( of course used on the "gon" ).
I've been hometheatering for about eighteen years.Since surround sound had no center ch.I have owned noless than ten subs,looking for the holygrail.Oh, boy. These things will shake your soul, period.I fear for my ears and floor joists.
Lets start with Harry Potter.The Womping Willow scene will bottom out the best sub.Not mine.That tree smashs the heck out of the car and my subs never even crack.How about The Fifth Element.OK the whole movie ROCKS,ROCKS,ROCKS.U2 rattle and Hum ROCKROCKROCK.Ice Age,when that poor sqirrle cracks the world, you do too.I can't say enough.Good luck.
