Subwoofers with room correction built in?

I’ll echo the last two posts and add that even the cheap 8033 from Dspeaker, which is only meant for subwoofers, works well, particularly if you dial in the woofers as much as possible (placement, crossover, gain, phase, etc.). I run such a unit from an additional line out on my line stage to feed the Dspeaker, which controls a pair of Rhythmik 15 inch subs. Those subs are not crazy money and really blend well with my hybrid horn set up. Note that the 8033 sums the bass for two outputs so no stereo subs (unless you have two 8033s or buy the fancier Dspeaker unit mentioned above). I don’t really care about that because I’m mainly playing LPs most of which are summed bass anyway and I'm rolling off the subs at 55hz on a 24db/octave slope. Pretty cost effective way to get synergy with a horn/hybrid that does not sound like two systems playing at the same time. It is seamless.

It's good to know that there are external DSPs that can be had for reasonable prices, but right now I'm primarily interested in hearing from those who have had subs w/ the feature built in.  Anybody else care to share?

Well the just of it is, the ones I built work great and the plate amps your asking about are very close. It's worth your while. Along with room treatment, DSP is a great tool and pretty easy to use..

Mic position is the key if you ask me? Right where your head is going to be.

I'm not saying you'll like the way it sounds though.. Really some people just don't like the sound. It doesn't account for OUR ears sensitivity or the lack of it.

Better off with it, than without it. That's for sure.. I use the PEQ function for a 50 and 70 hz bump works great..

Enjoy

No experience but lots of reading with almost universal love...the Dynamo series from Martin Logan. Anthem Room Correction built in. Full app control.

The Anthem Room Correction on my Martin-Logan Balanced Force 210 sub is nothing short of outstanding.  The difference between no correction and corrected is the difference between bass that goes in and out, depending on the note, and sound that is equal in volume as the bass player goes up and down the neck.  Quite beautiful.

I only have one sub though.  Perhaps it would be less noticeable with a DBA.
