Ok, some folks have been asking about 6 stacks, a few have asked about singles (for running a single 12 on each side of a small room)..... so weve been working on a modular design that can work out for basically any number of woofer (singles, duals, triples, quads, or 6 stacks). We saw something similar a year or so back when Rich built his 6 stacks.
These are cut from Medex, 1.25" side panels, 1" baffles, and .625" top/bottom modle plates. The actual cabinet top/base will also be 1.25" Medex. Medex is a water/moisture resistant composite, it's classified as an MDF but is slightly denser , approx 770 kg m/3 vs 720 kg m/3 with standard MDF. It is formaldahyde free
I've got a couple modules cut as prototypes. We went kind of crazy with the dowels, there will not be as many with production pieces. Final units will have 2 dowels for each joint vs the 4 we drilled ( I only used 2 per joint in the pics below)
Baffles are 1" thick. They are pre-drilled for woofer screws, have wiring pass thorough holes in each corner to eliminate going up and down with wiring, ( forward facing baffles will not have the pass through holes), and a .5" roundover on the rear side .
Top/bottom module panels are .625" thick. They've got 4 8mm bolt holes (one in each corner) for bolting modules together (these are skinned over so the plates can be reversed at the very top/very bottom of a stack, no hole will be visible at the very top/very bottom. The necessary ones will be drilled out for bolts before shipping.
There are wiring pass throughs on the rear side of the baffle.
These plates inset .75" from front and rear edge of side panels so grills can be inset (options yet to be determined).. There's a .125 reveal cut onthe front/rear edge to correspond with next module..
Side panels are 1.25" thick. Each will have .5" roundovers on outer vertical edges, a .125" rouindover (reveal) on inner vertical edges and outer horzontal edges to correspond with next modules.. Two dowels will match each top/bottom plate and also baffle edges.
Here's a sinle module from the rear side with the .125" reveal/rouindover cut around the top. Next module has the same cut on bottom. There will also be two vertical dowels in each side panel (both top and bottom) for locating subsequent modules and a base and top on each stack.
A pair with a mock base and top (some left overs I had lying around). Actual base/top will have .5" rounded corners and .5" round overs on top of base , the top.bottom of cabinet top.
NOTE: If you're thinking of veneering a set of these, we can disucss eliminating the ro's
A better look at the reveal between modules
Bolt holes were positoned so that after no rez is installed, they'll disappear
As mentioned, pricing is not finalized, hopefully soon. We've got to determine yeilds, source some fastners and there a couple little details we need to finalize as well. Likely these will ship 2 modules per box, maybe 1 when it includes a cabinet top and base.
So , for those who have asked, they are coming soon
