Most Musical Subwoofers?


I was wondering if any one had used/heard the Legacy Audio Extreme HD? Anyone compared these to JL Audio F-113 or F-112s? I'm considering adding subs to my system as my room has a suckout at about 40 hz that I'd like to fix.
Thanks in advance for any info/experience you might have. I'd be glad to discuss/talk over the phone as well. Send me your phone #.
Good listening,

Lots of great recommendations. I'll just add this one...

Seems like they could potentially match the excellent JL Audio units at a big discount. If this one's out of your price range I think there's a smaller sibling that might also be worth checking out. Best of luck.
The difference between high quality subwoofer systems pales in comparision to what the room does to their outputs. In the bass region, the elephant in the room IS the room.

Some have advocated using two subs, and I would join with them. Preferably, position them asymmetricaly. This way each will produce a significantly different room-interaction peak-and-dip pattern at any given listening position, and the sum of these two dissimilar peak-and-dip patterns will be audibly smoother than either one alone. This may seem counter-intuitive, but I can explain the acoustics and psychoacoustics behind it if anyone would like.

I strongly concur with REL as above...I have the Strata III with Vienna Mozarts.
Vandersteen woofers are also highly regarded both in sound and in value.
I guess I have to play devils advocate here and state that the B&W ASW 850 is the best I have heard so far for music and movies. I have it seamlessly integrated in my all tube system and the sub is located on the right side of the right speaker facing towards the same plain across the linear path of both speakers. In all of my measuring and experimentation this is where it sounds best.

Now I am ready to take the plunge and get another one to play around with and see how much better I could make the music experience. But one 15" sub sure does fill my room pretty good already when I need it to jam for rock music, I hate to see how two 15"s will do. For other types of music, the sub is omnipresent without a hint of its existence, except for deep bass energy when I switch off the sub EQ, Velodyne SMS1 and realize that a song had some more energy associated with it, but it is minimal in nature and the sounfield is more alive and vibrant with the sub in action.

So I know I want a pair of subs, I'm leaning toward JL Audio, what do you use for a high pass filter, since most subs only come with a low pass filter? From everything I've read, just using a low pass filter and trying to blend the sub with the mains, sounds problematic.

It seems like the Velodyne SMS-1 might be a good choice.
Would I need two for stereo subs? How good is its circuitry? I'll also post this question separatly.
