The box is designed and built by me, a cabinetmaker turned remodeling contractor. The amp and driver design is the brainchild of Danny Richie of GR Research and Brian Ding of Rythmik Audio. I started a thread about this when the idea was gestating. You can find the saga here:
http://www.audiocircle.com/index.php?topic=84765.0As is sometimes the case with my projects, the further I get into them, the more I lavish on in terms of ultimate function, sometimes this extends into the cosmetics, as well. This is one of those projects.
My goal was to make the deadest box possible without getting into ridiculously exotic material. To control resonance, the “core” structure is built with MDF in two different thicknesses and Baltic Birch plywood in three different thicknesses. All assembly was done with polyurethane “thick” glue. Super strong but has a somewhat flexible glue line. This has a slight decoupling effect on the individual pieces. The amp is separated from the driver compartment to ameliorate any effects from the internal pressure or vibration.
This alone would have made a very dead box, but I added a “wrap” of sand to absorb cabinet vibration. After that came the 2 1/4” sides and 1” top and bottom. Yep, it’s heavy. The end result of all this is nothing…that’s right, the box contributes nothing of its own to what is being fed to the driver. Irony at its best!
Time spent on this project was considerable…over 180 hours to build four of them plus a bunch of time futzing around with the copper gilding to evaluate feasibility. So here’s the deal; I built four, I’m keeping the gilded one and perhaps another. I’ve got two in primer and the one pictured ready for No Rez, amp and driver.
If you’d like the completed box (black with gold sides shown in the thread and pictured here) it’s gonna cost you $1800. There are a couple of minor blemishes on this one which I’ll attribute to learning and am discounting because of it.
If you’d like something different, I can finish one or both of the two currently in primer with base coat/ clear coat urethane, your choice on color. Fine sanded and polished like the picture. Price tag will be $2000 ‘cuz the learning’s behind me now

I can mount driver and amp if you'd like.
If you’d like to have it shipped, I can build a bullet proof shipping crate, but weight will necessitate truck freight.
This is getting pretty long winded, so if you're hankerin' to own a gorgeous, no compromise sub and would like more pictures, info, or whatever, pm me your phone # and I’ll be happy to call and talk to you because I type slow!
