Most Impressive, Beautiful Veneer for speaker baffles

thadman · 15th August 2007, 11:06 PM

I'm entertaining the idea of going dipole and rigidly affixing the drivers to a 10mm (60 x 18") sheet of lead. The sheet of lead will weigh around 175lbs and should have a resonance below 10hz (fyi lead for a given thickness is 95 times better at diminishing sound transmission through its medium than plywood). Since the lead will mass dampen any resonances, the choice of a nice wood or veneer adhered to the lead seems to be an excellent choice for aesthetics.

What is your favorite veneer/wood if you could use any (discounting its resonant behavior)?

Tigerstripe maple, or maybe walnut burl. But then ask me tomorrow and I'll have a different one.

ROHS veneer.

I wasn't aware that veneer came in lead free varieties!

Are you thinking about 1/2" material for the sandwich? I think the lead, even though it is 1 cm thick might still have a certain amount of flex to it and that it might take that much bread to control the meat. Does that sound reasonable?
