Thanks for that KuanJB, I'd not seen that, nor heard the G rationale behind their systems.
It raises some questions about what I've designed above, and i think i might go back to the drawing board and rework it somewhat.
I'm thinking:
- Pull back from the Post mounting locations for safety's sake
- Reduce chamber number, but increase size, currently drawn as 5/8" might go up to 3/4" or 7/8" (15.8mm, 19mm and 22.2mm for the non imperial speakers)
- Rework the control cavity to reduce in size/match the lower bout curve.
We shall see, first we draw, then we measure, then we measure again, and again, then we pontificate, then we dither, then we cut. after which we say "Awesome!" Or we say "@(#&%!!".
