Two Subs?

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.

Rodge,

A kindred spirit: room correction, Tommy Emmanuel, and Frank Vignola. My Ryan Thorell archtop is one of my favorite guitars (tho it's not the Vignola model, it has a strong family resemblance). And I fully agree that when you clean up the lower registers via room correction, the personality of the guitar being played is much more recognizable.

Rodge - Thanks for the tip on Dspeaker. I've gone to their site and products look interesting; so I sent a few questions. I already have a nice preamp and don't really need a DAC; so, I'm wondering if I should just get the Anti-Mode 8033 instead of the Dual Core 2.0. Hope to get some answers next week.

Rockyboy,
I had the 8033s for the subs and graduated to the Dual Core from the distributors request. The 8033s was very good, but the D/C took the sound quality up many a notch. The D/C has USB and Optical SPDIF inputs and an Optical SPDIF output. Therefore it can be installed using it in Pure Digital. Use either the USB or Optical inputs and the Optical out to your dac. You can run the necessary room corrections and use the dac/preamp/amp combo of your choice. The room corrections are done in the digital domain and will continue down stream to your dac. The D/C is a very user friendly piece and can find it's way into most systems.
Heck for the cost of one, you might want to check out it's dac and pre against yours and decide to use it that way. That's what I did and I'm very happy.

As noted above the D/C will sound better with a quality 12v dc linear power supply or 12 dc battery power supply. I checked with Dspeaker and a 12v dc LiFePo4 battery fully charged is 15v dc and will work with the D/C.

Hope this helps.

So true!
Brings a whole new experience to the table.
I never knew Rodrigo y Gabriela could sound so good and precise. Like sitting third row center and getting the live sound from the stage!

Wow! A Thorell Archtop!
Serious player, no doubt! :-)
Nice ...very nice!
