MDF works just fine as long as you have proper bracing. How you build your cabinets is more important than the material.

Ply is nicer to work with. It's easy to stop the sound from the rear of the drivers getting out, the question then becomes what do you do with it now it's trapped inside?

Why trap the sound inside? What about a plywood, sand-filled, open baffle!

You are, of course, moving part way towards a logical conclusion, however, the OP did mention something about speaker cabinets.......

MDF is a carcinogen. The dust is very dangerous! Use ply wood everytime.

I've read in the past that 13 ply Baltic birch is the one to use. Any thought. I don't like carcinogens.

13 ply BB is 18mm. It is avaialble in a range of construction quality. We used lots & lots of it (and 15, 12mm) but switched over when we found the quality of the BB we were getting was getting poorer*, we switched to the Murphy Ply birch plywood which was of a higher quality. A quality Baltic core which they skin with maple veneeres (sp ominal 18mm gets 15 plies).

*(BB can come from Finland, the Baltic States, Russia & China (list in our experience shows a general decrease in quality).

The BB we were getting did not cost a whole lot more than decent MDF.

You spent big bucks on the drivers, don’t skimp on the final box.

I'm looking forward to picking up a sheet of this to work with. The veneer on the top and bottom match the end grain.

planet10 - Agree with you on the BB quality declining, my favorite (although it has gotten expensive), is State's Appleply. (both States Ind. and Murphy are in my home town)

Another interesting material is PaperStone - in black would look nice as a baffle.

Good materials are easier to work with than the cheaper stuff - flatter, consistent thickness, etc.

I can’t stand mdf, I will not use it for DIY due to the dust plus weight plus wear and tear on tools. It’s banned from my house, not even in store-bought furniture, baseboard trim etc. Bloody horrible stuff.
