speakers/sub

Drew, that's odd, when I tried the "learning" subs (velodyne specifically) when I had a system in a very small room in the basement my experience was that sure some manipulation could affect performance in specific areas (frequencies), but the sub just wasn't very good.

Applying filtration to a sub that just doesn't produce a strongly musical sound performance and the ability to stay caught up with my speakers (at the time a pair of Wilson Audio Duettes) didn't do it for me.

All the digital manipulation didn't make up for a somewhat lacking sub in the first place.

My recommendation is to find a sub that has high performance characteristics and good speed, whether with or without all the digital filtration/adulteration components built-in.

A finely tuned Yugo is still a Yugo and no matter how good of a condition its engine is in, it's performance will always be limited.

I agree with Drew.

The best bet that I could point to is either the Velodyne SMS-1 sub-controller (app $400, I use one in my system) or the SVS Audyssey Box (app $800 plus the cost of the required external active cross-over). The specific choice of subwoofer (while important) is -IMHO- less critical in a small room than the use of room correction.

I will disagre with Drew's "auto calibrate" advice - for the most part. The Velo automatic option sucks, it is primitive and doesn't even scratch the surface of what the SMS can do. In fact, all of the auto-calibate systems that I've heard come up short of manual calibration (although they are way better than no correction at all).
IME, manual correction - while a major PITA -is still the best way to go. Disclaimer: there may be good auto-calibrate systems out there which I haven't heard.

As to the sub choice, I use 12" Rythmiks. Very good sounding, very flexible (adjustible Q), and reasonably priced.

Good Luck,

Marty

IMO ,your getting bad advise outside moving the system to another space.I doubt a room 10-13 room has"wonderful bass"as stated(unless youve never heard a really great system then maybe).To suggest a sub choice for a 10-12 room is quite comical as your basically listening nearfield,again My opinion.

Mission, You are just speculating. If you haven't heard my system, then it surely is your opinion.

Mission,

Have you heard any of the DRC systems (ala Audyssey). If not, you may want to audition one. Try it in a small room. I can't guarantee that you'll like the result, but I'd be shocked if you couldn't hear the difference.

As Drew notes in his post, a corrected sub will fix a lot of problems between 40hz and 60hz and, as he also pointed out, it will address room induced issues at and above 100hz, if crossed high enough to do so. IME, if the program material has any information in this band, you will hear those room effects very clearly -even in a small space.

I made the direct comparison some time ago in a 10'x12'x8' room and the delta between the DRC bypass and DRC engaged was DRAMATICALLY audible.
