I Need Help Picking a Sub


Hello all. Right now i have put together of a somewhat decent theater system in my small living room. I need help with a sub woofer because i dont know what to buy. I am giving myself a cap of $1400 for something used on audiogon. I have Martin Logan ascent front and center speakers. I have a sunfire pre and 5 channel amp all of which are balanced connections. i am looking at the revelB15 sub or perhaps a velodyne DD series. because my space is tiny i was thinking nothing more than a 8" woofer but someone told me to stick with nothing lower than 10" for clarity. i could use some help from those audio pros out there.

Martin Logan makes great subs. I use two Martin Logan Dynamos and they are very good small footprint subs.
I agree with Rcrerar and Cruz123; I currently own the ML Grotto and have owned the ML Depth; they both pack the punch for HT and are fast enough to keep up with your Ascents. You state your room is small and your budget $1400; my two cents would be to go with a Grotto which you should be able to get on A'gon for around $600; if it is not enough for your room, get another one. As another option, I currently have a Grotto and a HSU VTF-3 HO in my HT; I run both during movies for the explosions etc., but when I listen to my concert DVDs, I turn the HO down somewhat and let the faster Grotto do the majority of the music. You should be able to find an HO for around $650 on A'gon. This gives you flexibility- good luck in you search!
To tame your small room with pinpoint accuracy of low frequency tones the best sub choice you already made is the DD go for a used DD 10 or you can go for the cheaper velodyne spl 1000R. both have excellent equalization option.

The JL Audio may produce a little more bass at high volume which you seldom may use but the sound equalization settings are not so great.
The james EMB 1000, 1200, 1500 are very depending on room size, the ML ones mentioned are also great, and the JL Audio, and Rels.
If I had ML speakers, I'd sure look at ML subs first.

But I really do like my DD15... but sometimes wish I had gotten the DD18 instead.

Subs aren't about loudness so much as they are about depth.... and you can use the volume knob on them, ya know. Get a DD12.
