Two Subs?

I've never heard the DSpeaker Anti-mode duocore, but it gets good reviews and (I believe) shows room analysis as well as providing correction. Underwood HIFI sells it on-line, and - I believe- provides an an-home evaluation/return policy.

Good Luck

BTW, I believe the cost is just over $1k, so I'm not sure it's "on the cheap" for you.

Bo...I can only assume things about your taste in sound quality based on your posts. When you claim to use subs crossed over at 140hz and then you filter the hell out of them with room correction, I can get a good idea of what you're looking for. Likely a sound similar to a Joe Bonamasa concert. When you make ridiculous and condescending statements about "coloration" you also strain credibility...I use a REL high level input which replicates the power amp tone, and any musical tone cues that would reveal innacurate coloration are absent at the low frequency points the REL produces with distortion inaudible when driven at reasonable levels. If you had listened to the things you supposedly sold, even with the unsophisticated and clearly untrained ears attached to your thick head, you might understand something about basic acoustics, musical accuracy, and what professional musicians and sound engineers often hear.

I use the Dspeaker Dual Core 2.0 in my 2.2speaker system. I also use it as the Dac and preamp. If you use it this way I would advise getting a good 12v dc linear or battery power supply.
My 2 subs are Shelby+Kroll Woofer Monitors which are a 10" down firing design.
My room is 15.5'w x 21'l x 8.25'h man cave/office.
The Dual Core can measure the room from 20hz-20kz and you can also choose what frequency you want to measure. From there you can make the necessary adjustments for the bass you like, and keep them in 4 different profiles that are easily accessible with a push of a button on the remote.

From the measuring tool I saw that I had a huge valley or "hole" from 35-55hz and a serious peek around 70hz. By placing the subs in the corners, turning up their gain,and running a 200hz correction the hole began to close and brought down the 70hz peek. I continued increasing the gain, doing corrections, and measurements until I got the bass to -1.5db from flat to about 120hz!
No cutting with extension beyond belief!

I never knew how many deeeep notes that Victor Wooten was using in Flight Of The Cosmic Hippo (Bela Fleck and the Flectones), but I do now!
The bass and drums on Hotel California from The Eagles "Hell Freezes Over" is deep,clean, focused, and very extended.
All of my music even single acoustic guitar music by Tommy Emmanuel and Frank Vignola has body and depth that are intoxicating to listen to. Hearing INTO the guitar body is something I was never able to do before installing the Dual Core.
I could go on and on, but if you are using 2 subs the Dual Core 2.0 is a must to get the most out of them without having to move your subs all around the room.
Oh and there is an adjustable subsonic filter so you won't fry your drivers.
