    In terms of light weight, 2x12 or 1/15 cabinet construction, what is the recommended material ? This material would be coming from a specialty wood supplier so Marine and BB are available. I'm thinking 9mm BB using front to back bracing. Are there better choices ? I'm not necessarily thinking low cost in this particular case ...

    Even with extensive bracing 9mm won't cut it, 12mm is the minimum. Don't waste money on marine unless you plan on sailing in your cab or you live in Venice or New Orleans.

    and 12 mm is like 1/2 inch. that is what I was actually thing (about 1/2 inch) and the wrote 9 mm ... duh. Glad I didn't do that a Crosscuts, it's about an hour 1 way ...

    I used 3/4" on mine...and my speaker baffle board is 1 1/4" thick.

    Don't skimp too much unless you plan on doing some heavy duty bracing. Remember that your cab is going be taking on a lot of vibration. I mean A LOT.

    Biggest thing is to get void free. If there are any areas that have knots, or spaces, it will have an adverse affect on the overall quality of the sound.

    I use half-inch almost exclusively and it's just fine when you properly brace it, like this. It's more work than just using 3/4 but the result is lighter and stronger.

    Yeah...if you go lighter than 3/4" you will need more bracing.

    I used 3/4" and still braced it. My 210 cab is solid as a rock, but still quite light.
