So what sub are you using for your Home theater?

If you are a fan of 18" sub drivers, believe it or not, the Triad Platinum sub (or subs in my case) are VERY musical, and of course can hurt when needed for home theater.

I swapped out a pair of HGS-18s, and have been the owner of a pair of Aerial SW-12s. The SW-12s are probably the best subs I have owned/heard. AT TIMES, I didn't feel one was enough for some very serious levels of movies, but two will seriously knock your socks OFF! The Triads, in pairs, are all of the HGS-18s (one to one, the Triad won't reach the same SPL's) and are one of the best values on the 'sub' market.

Triad, a home theater speaker company that has designed a sub that is a rather 'small' box 18", sealed cabinet, powerful amp, and just a good, quick, clean bottom. Everyone loves a clean bottom.........

Stehno - chime in about the Triad Platinum.

I use 3 Vandersteen subs. 2 - 2Wq for the front speakers, 1 - V2W for HT and located in the back of the room. My system is used 50/50. Same comments as SDCAMPBELL about Vandersteen.

I guess it depends on how big your HT is.
My AV room is 12ft x 26ft. kinda a Big long hallway.

I use a Definitive Technologies ProSub 200. Its only 250W rms, but it shakes the hell outta my HT when needed. Good dispersion, and pounds out some very good concussion. I honestly cannot see any reason to get something bigger than this unless my listening room gets alot bigger or i feel like cracking my foundation.
In the beginning of "Attack of the clones" when the luxury liner escorted by fighters flys overhead, it gave enough power to rattle a glass off my coffee table. Its not "Too picky" about placement either.

Works great with music too. Gives great impact, very tight control and doesent sound too boomy.

Ive auditioned Subwoofers from Infinity & Velodyne that cost quite a bit more and still, IMHO believe the ProSub 200 outperformed them in many ways. If there is a local "SoundTrack" audio store, you can check these out there. They also carry the Sunfire brands as well as several others.

MSRP $549.00 So it doesent break your wallet

Sunfire True Sub.

It works, but even with a "cheater plug" it puts out a hummmmm. I only use it with movies (nice!!!), so its un-plugged most of the time.

I use an ACI Titan II for my home theater.
