High end sub for big room. Suggestions?

I have transcendance speakers also. I talked with the vp of Hales at lenth about witch sub would be best and He urgered me yo buy a Rel . I did and am very happy I bought the Stadium II 2500.00 retail now the III is 3000.00 . They are the best integrating subs that I have ever heard , go to there web site. Check reviews at audio review. The Stentor is the next step up . Don't be skeptical about the power either My sub is only 100 watts My room is 18w x 32l with 12' cielings and it fills it just great.

I use some Entec L2f woofers with Rockport Syzygy speakers in a room not much smaller than yours, 16' x 24' x 8.5', but I would sure use two of them just outside the Hales....The presentation becomes about 20% larger than running the Rockports full range (they fall off the map in the mid thirties).....The Entecs will image in the bass as I can turn off the main amps and listen to bass image all over the place here.....They also have a 1hz notch filter wherein you can notch out the room modes, the nasty ones in the 70s and 80s.....Demian Martin hasn't built these in years, but I can put you in contact with him if you like as he might be able to find a pair for you.....

I also have a pair of the Entec subs mentioned above. Use them with Wilson WATTs. They are certainly better than the Puppies.

However, for movies and really deep loud bass I wanted even more. I've chosen the Stryke HE15, which by all accounts is up there with the big Krell and Wilson units.

Here is link to more information:

You may find the price pleasantly surprising.

Entec is the way to go.

Krell makes probably the best subwoofer ever. But that is to be expected!
