I can get some birch ply locally but unfortunately it only comes in a maximum thickness of 8mm:
Plywood products ? Aircraft plywood ? Birch Aircraft GL3
They also call it "aircraft ply", thus will likely be charging an arm and a leg for it.
Are there any similar ply alternatives? This is the range I can choose from:
Plywood suppliers ? huge range of plywood products, MDF & wood panels
And a recommendation of thickness would be great. Thanks

Their "Marine plywood" looks like an excellent candidate to me:
Plywood products ? Marine plywood ? Decorative Cedar Marine ...

Density on its own is unimportant. If 2 materials are the same stiffness (some other properties play a role too), then the less dense (ie lightest) will usually have the advantage.

Yeah I've read that. Thin cabinets, heavy damping, pushing the resonance lower. There was a thread on here once that discussed in a lot of detail, but I can't find it now...
If in doubt, brace the hell out of it (providing you don't want 1/4 wave style action) and it tends to offset the difference quite well.
Don't know about across the pond but if I couldn't find this local I'd go here.
This is a multi layer B-BB grade, not marine grade, which would be very expensive.
e.g. Single Piece of Baltic Birch Plywood, 18mm - 3/4" x 24" x 30" - Amazon.com
That second site on your OP looked liked they had a lot of products, maybe send them a email.
Thickness? 18mm-3/4" is very common.

There's some discussion of the issues involved here:

How crazy are you planning to go with this project? Are we talking all out, no holds barred or rather a nice economy build?
Not very exciting but you can go MDF with epoxy coating and that'll take you quite far. Personally I'd like to go Birch-ply in my next build but you sort of start out with your goals and limits and then take it from there.

Its a 2 way monitor with Scanspeak 15W/8530 and probably Morel tweeter. I think plywood will be less labour intensive than MDF since I can finish it with a light stain rather than veneering or painting. It looks very nice too imo.
So what is it about Baltic Birch ply that makes it so popular? Is it the stiffness, density, flexibility...?
