The best Subwoofer

if you dont mind ugly try jbl pro 4719. it makes the termites run for cover. i have one with a krell kst 100 stapped mono in my theater. it will destroy other so called subs . it has awsome detail for music to . i know some of you think i am nuts but every audiophile who has heard it could not believe the sound. 99db at 1 watt . i have heard the krell beast. yes it is bad to the bone. but get out your wallet. i would put the jbl against the krell . most theaters use jbl pro. i was in vegas last jan . i saw the dts setup jm lab grand utopias 5 of them. halcro amps. and guess what subs.

No longer in production but the last version of the Entech LF 20 was quite impressive. Two 10" long throw woofers, each with its own amp built in. The active crossover built into the subs allowed several frequencies and bass boost if desired. I am using stacked LF 20's (two LF 20's on each channel) with Crosby Quads and they mate seamlessly. In my room, they are plus 3 db at 26 hz. As an aside, their external passive crossover was terrible but easily replaced with two Teflon caps and a TKD pot.

I also have Entec LF20s. They are the best I've heard. I'm moving overseas and can't taker mine with me, which I deeply regret, but they are great.

I own a pair of Talon Peregrines and am currently researching subs as well. A great sub that I had the opportunity to listen to while auditioning the Peregrines was Talon's own sub-The Roc. Not cheap, but very powerful and precise.
A conclusion I am arriving at is that a sub must have an amp with an outstanding damping factor. This seems to be achieved only when using a brutally powerful amp, whether you go passive or powered. I think I'd like to go passive. Mainly because of the flexibility and because I could just get a Bryston 4B ST to drive it and be done with it. Outboard crossovers of high quality are not cheap however,and with the extra expense you go through to achieve this , you could have gotten yourself one hell of a pair of floor standers that do not need the addition of a sub. The answer for me is pretty simple, just go with the Roc. System synergy and all that...but for you, I think it may be more difficult. The Muse Model 18 is probably the best way for you to go. Besides, Kevin Halverson is probably giving them away along with the cards.
Best wishes and good luck. Be sure to let us all know how it works out for you.

Dunlavy! Has anybody seen their new offerings? Can we say "huge"? Their new top of the line sub towers are actually designed to be paired with the SC-VI speakers (as if these speakers did not go low enough already!)

Their top sub weighs in at 600lbs a side! ,with 4 of the same 15" woofers that are used in the SC-VI speakers.

That's 8-15" woofers total! They are rated at 95db/watt @ 1 meter.

I would not want to try to survive a full power assault of a pair of SC-VI's along with these two monster tower subs. Imagine a total of 10 high efficiency 15" bass drivers in a pulse coherent configuration capable of inflicting permanent damage to your ears, and potentially your walls and housing structure also. We are talking about serious overkill here.
