How much do you have to spend, to get a good Sub?

If you are buying new, a good subwoofer that will be relatively easy to integrate into your system (which requires, as others have noted, that the subwoofer have some sort of automatic room correction software) will run between $2400 and $3200, minimum -- cost goes up from there for bigger drivers and a little deeper response. Good brands to look at include JL Audio, Velodyne, and REL. I would caution against buying an off-brand without auditioning it first -- a lot of them are just glorified boom boxes.

What's your budget? For music I'd go with a pair of sealed subs. You can get a pair of SVS SB12s for $1149 and free shipping. Tough to beat I'd think. I echo Marty's point about incorporating some form of integration software. Best of luck.

I am thinking of a M&K X10 sub ( M&K inventors of the Sub) any thoughts?

I have to agree with Soix on this one. The performance/$$$ ratio is very high with SVS.

Check out SVS SB-1000,at $499 it is a real bargain. They have a 45 day return and free shipping. They are a great company to deal with. I used that sub with Harbeth's with great results.
