What is your favorite material for loudspeakers?

The Baltic we use is Finnish I buy by the pallet to save $. If you source plys from most home centers its Chinese and lamination on this ply are terrible. Sometimes I can pull Chinese plywood apart with my hands!!!. Ive tried MDF ply, HDF ply and others in layers still to me Baltic and veneer with French polish gives best results for my loudspeakers. But my good friends a TT nut he uses layers on his plinths. I use aged hard rock maple for bracing this gives best tone. I have build solid hard wood cabinets but most split after a bit of time ,if I use hard woods I use over ply. Thank you for the posts. And happy listening.

Johnk,

Your thread has got me thinking about the possibility of building the ProAc 2.5 clones using Baltic Birch plywood instead of MDF with veneer.

I know this would alter the sound of the speakers from their original intent. What are your thoughts on the sonic influence of this wood for box construction?

Thanks,
Dean

MDF stores energy releases as slight delay adding coloration to sound if fully braced you can work with it. But baltic birch plywood doesn't store releases energy so the coloration's of birch plywood are pleasant the coloration's of MDF tend to be narrow in frequency and can add a unpleasant delayed coloration. So a doubled 3/4in Baltic cab for your proac would be a improvement in sound quality. The French polish penetrates veneer so resonates more even in frequency and at a greatly reduced level.

Thanks, Johnk. I'll look into it.

Not sure its is my favorite, but my VA PO's in the Big Leaf Quilted Maple are stunning! The fit and finish is on par with the very best I have seen.

Sonus Faber does some nice work too..
