musical subwoofer recommendation for 2-ch


Can someone recommend good subwoofers for 2-ch listening? I recently purchased a pair of very articulate speakers made by JAS audio. They have small woofers and so they are fast but do not have sufficient low bass.

I have a 15" Velodyne SPL-1500R. It is very powerful. But it is too slow to match up these speakers. So I'll save it for HT applications.

I am thinking to get two 10" subwoofers and connect them to the speakers. Is this a good idea? What are the good subwoofers I should consider?

Thanks in advance.

I'm using a Martin Logan Dynamo with great success. It has 10" aluminum woofer that's very fast. About $600 or less. The next step up, the Abyss has a 12" woofer but is the same design. Both can be set up to fire down or out.
If I use just one sub, will it impact the channel separation and sound stage? My main speakers' specs claimed a -3dB point at 35Hz. Since the woofers are quite small (twin 6" per channel), I don't get the presence of low bass from them.

Which REL should I get?

By "slow", I mean the bass does not have texture. For example, you don't hear all the details in drum rolls.
Vett93, I am using a pair of MJAcoustics Ref200 with my Wilson Benesch Arcs and they are working out great. Fast, detailed, never muddy, manageable and a good blend with the speakers. The dual crossovers for the high and low inputs and a programable remote is a plus. Check out Jason Scott Distributing for info and give them a call.
Here's one you might try to find on the used market.

I would be careful about your assumption that you have a "slow" sub - unless it's a piece of crap (and yours certainly is not) there is really no such thing. Check out this article:

I think you have a sub integration issue that likely has nothing to do with your fine sub. Your comment about drum rolls reinforces this - I can't think of a drum roll that your sub would even produce or that you would want it to produce given your speakers. I guess it's possible if you have it crossed over at it's max upper frequency but even then I'm not sure.

I think you either have speakers that don't do what you want them to do with your kind of music at your listening levels and/or you don't have the sub integrated properly - the combination of placement, volume and crossover is wrong. I would investigate these things carefully before shelling out more cash on a sub that someone on a forum claims is "really fast" and likely will not fix your problem.
