Is there a particular wood joint that would keep the enclosure rigid and rattle free at high volume and is birch ply a good choice of wood ?
Hey phooter: I can only give some advice on one question.
Birch ply is awesome for your project, it's pretty easy to work with and it'll hold up really well. I bought a fat slab from Chamberlins which was about 2.3 x 1.2 and it put me back around R350-00 and they dropped off for free. I got it a bit cheaper because it had some paint messed on it. Makes no diffs.
For making a cabinet like this, I strongly believe in finger or box joints.
They are pretty simple to make and are Über strong, just takes some patience, I've done joints using a jicksaw once and while it took ages, the box was bullet proof.
I'm sealing the joints of my 4 x 12 cabinet box with a product called cottonflox, it's a chopped up fibreglass strand mixed with resin that dries rock hard and sticks to ply like poo in a shoe.
