I love Hot Rod Black, which is offered by quite a few companies. The stuff I went with is John Deere's Blitz Black, in a rattle can. It has a sheen less glossy than satin, but not quite as flat as matte.

Has anyone ever tried (well, I'm sure someone has) making some kind of sandwich of MDF - like maybe MDF/Sheet Aluminum/MDF, and building speakers with that, or thin granite tile material sandwiched (i.e. www.lazygranite.com)?

If dead and stiff is the goal, wouldn't that achieve the goal better than MDF alone?

A LONG time ago folks used to pour sand into sandwiches of MDF (i.e. between two layers).  Stuff was very inert and dead sounding (minimal resonances) but it weighed a lot. Even bookshelf sized speakers were heavy.

I can make it real easy for you guys exploring cabinet materials. Well braced MDF and No Rez.

In the 1950's and 60's, some of the original WWII-generation speaker designers offered huge bass-reflex loudspeakers with built-in chambers for filling with sand, to damp the large, unbraced enclosure walls. Bozak was the best known of the type, but there were others. Danny Richie has designed a double-walled, sand-filled sub enclosure, the build plans for which are pictured in the details of the GR research 12" driver for sealed-enclosure use.

Sand isn't that great. It doesn't even really do anything in a lot of applications, and in speaker walls it's one of those low returns for effort.

Actually it is really hard to transmit any kind of resonance through sand. It just dissipates into the sand rather than transmitting it. I'd have to say that in many applications it is an excellent return for the effort.

Round three.
My vision was to have these look like photos I've seen of lava flows where it's black on the surface and the molten lava is visible through cracks. While not quite what my mind's eye saw, they still look pretty striking. These are all somewhat experimental anyway...

What shall we call these? Magmas? Cracked Up? Bad Trip? Y'all tell me...

Primed white so red would be bright as possible







Then red...RF RED, you figure it out :wink:






Hard to see here, but I mixed some yellow pigment into red lacquer to move color more towards orange and shot the corners only fading into red field






Then yellow and a touch of orange pigment in clear shot right at corner






Black primer in Crackle Lacquer. First time I've used this stuff other than samples leading up to it. It's a little bizarre to watch thing unfold and the results are difficult to control







The yellow didn't turn out quite like I wanted, looked more like a dying dandelion than lava.  So I decided to tint clear lacquer to shift it toward red/orange to see if I could change it a little. Two coats of tinted made it mo betta. I'll let this dry for a day or so and give it a coat or two of clear. Close up better shows what they look like, wrong time of day to photograph and getting reflection that kinda washes things out.
