In other words, Jack the Driver part of the panel up, and move an entire NEW speaker under it!
IMO, however, 'braced' stands made of metal COULD induce more problems than they solve.
I'd go for RIGID wood, and as light as possible. 'Ingenious' design trumps brute force.

Interesting opinion. Since Magneplanar has been using short metal stands in production speakers since the beginning, it's doubtful that increasing the rigidity via metal bracing would introduce significantly more problems than the shorter stands. That said, I see no reason why light-weight, rigid wood stands wouldn't work well too.
So, which kind of exotic wood bracing do you think produces the most balanced sound field?

I don't have a large enough sample. The Wood Framed MMGs I heard were terrific. And easy on the eyes.
My goal would be to RID myself of the MDF in any form. Wood is a natural composite, but I may go the REAL fringe route and use PlyBoo. This is BAMBOO PLYWOOD. It is fairly expensive and some of it only comes in a 6 foot sheet. I've experimented with small samples and it is dense and difficult to machine. You MUST have extra sharp tooling. Bamboo is FULL of silicon which is harder than a whores heart and EATS tooling.
Given careful layout, I think a Single 4'x6' sheet will be able to reframe a pair of 1.6 panels.
However, I'm thinking of NO room for crossovers will be than be line level. Also, instead of metal
L brackets holding the panel to the base, I'll use ball or roller bearings to couple the panel TO the floor and only 'locate' the panel to the base with NON-LOAD BEARING methods. The panel back suppor will be a triangulated truss type arrangement. Such divisiion of area creates short coupling of great rigidity and minimal weight.
I'm including a 'concept' drawing which is NOT current. I'm 3 generations PAST this drawing which I used only to SEE it for further mental modeling. Ratios of sizes is important to diminish IN PANEL standing waves. That's part of the evolution of the idea.
