You could use mdf....... most folks here don't like it, but can save a lot of money and if you have a local diy store they may even cut it for you. ...
I have made speakers with the moisture resistant mdf - denser and harder than regular and less dust when cutting. Still takes some bracing though to really sound good - I'd brace more than shown in pics so far if using this material. Probably even then not optimal for the last smidgen of performance, but cheap enough if that is needed. Not totally horrible. 🙂
First ones are out in the wild.

An externally hosted image should be here but it was not working when we last tested it.

The baffle perpendicular to the floor on those? Or is it just the picture?
With the driver cutout like that you may have trouble getting the driver to seal.

Just the picture. They are as drawn. With those annoying angles on both ends!
There is still a lip. But about 5mm or so. With the rear driver cutout chamfered there isn't much material left.

That might catch the 1st seal on the gasket, won't reach the secound one.
Maybe Chris could post a pic of the A10 cutout in the FHXL he is currently veneering.

Full disclosure - I experimented with a single layer of 18mm ply for baffles on these, without chamfering the rear side of mounting hole. While this is the opposite to approach that many builders are using, it seems to work fine. With a high quality multi-ply, and carefully sized pilot holes and pre-tapping with the MA supplied screws, I think the 8mm of core remaining after rebating is sufficient.
I wouldn't to this with A7s and 18mm baffle.

For some reason I can't see BackinBlack's pictures so here they are again...

Any interest in sealed enclosures?
I'm designing some for a client now. Most probably to be used with the Alpair 10.

I happen to prefer all the Alpairs I've heard in vented or BLH boxes, but why not. I guess the size would depend on the intended application - modelling suggests you can get pretty tiny with either of the 10s if you plan on adding woofers as high as 110 -120 Hz
OT a bit from that question - any reason why you've not thought about a CNC kit for the FH3? The A7.3 sounds quite wonderful in that one - indeed, my favorite for that driver when floor space is available.

They exist elsewhere, although I believe inferior in design (driver pilot holes, slots, terminal mounting etc)
If there is interest, I will make some...?
