Who are some of elite sub woofers?


Looking to replace Klipsch 12d

So many choices.

I have a SVS SB-4000 with My Spatial M3-TurboS speakers and the SB-4000 is fast enough to mate perfectly with my OB speakers and I am very picky. For $1,500 I’m thrilled with them.

This kind of irrational, illogical, and kneejerk reasoning will severely limit, restrict, and confine your ability to improve, refine, and advance you’re Music Reproduction System.
I have a SVS sealed sub in my system. Gonna buy a second one soon. Very satisfied.
Plus one for a Rythmik or SVS. 
So, Millercarbon, you have low end that really sucks from full range speakers where you're locked in on position. And the cost is crazy for true full range speakers. 
Don't know what subs you've tried but, obviously not the right ones.
Right, harley. Because of the physical impossibility of EVER finding the right ONE.

Its simply physics. Because bass frequency wavelengths are much greater than any residential listening room then any one sub source will inevitably create lots of lumpy bass. Equalization can't really fix this, for the simple reason it can only work at one location. So whatever boost equalizes that one location that needed it inevitably boosts in other locations that don't. The resulting overhang from excessive energy at those locations loads the room creating muddy bass. Which people then try to damp with tube traps, a never ending process of slapping band-aids on a problem that cannot in fact ever be cured because it is inherent in the physics of waves and walls.

Duke says it better but after having read through a lot of the research and corresponded with him a fair bit now I am confident that is a pretty accurate summary of the problem.

In fact as I may already have said elsewhere this exactly matches my experience across many rooms and speakers and years, although I never really brainstormed the answer. All I knew was no matter what speaker and no matter where it went and no matter where I sat the measurements and sound never ever would be right. Of course not. Because it can't be. Not with just one or two subs.

The problem is not which subs are used. No single sub can ever get there. With four subs however suddenly it becomes easy!

That is why I've just ordered four of the  Morel Ultimate UW 1058 10" Subwoofers from Parts Express. These are some outstanding drivers and they have them right now on a hard to beat deal that gets you a quality sealed cabinet included for free! https://www.parts-express.com/morel-ultimate-uw-1058-10-subwoofer--297-130

There's plenty of MDF just sitting in my shop, right beside the table saw, and the router. But free is hard to beat. 

It'll take a while to get here, even longer to find the time to it all together (April, more'n likely- but couldn't let that deal slip by!) but then finally, finally I will have some world-class accurate smooth powerful and tuneful full range bass.

Someone will I'm sure be happy to buy my Talon Roc. You want one? Its at least as good as any of the other miracle subs people seem to think work so well.
