massive brass plate for isolation

I haven't tried a massive brass plate, but I'm not sure it would be awesome. I would think it may have more of a tendency to ring or resonant sound on it's own. I could be wrong, as I know some have turntable's with 75 pound brass platters and no complaints. However, I'm happy with 2-3 inch think slabs of maple wood with brass cone footers.

Cheers,

Dissimilar materials used together are going to work the best. Sistrum was making a rack our of massive brass shelves and legs, that was supposed to sound great, but I don't know if they ever got off the ground with it...

Mixing materials with different resonant frequencies will offer the best solution when it comes to building a rack, or shelf. Try some alternating layers of different materials and see how that affects the sound...

Keep in mind cymbals are made of brass. They ring. Size determines
at what frequency they resonate at, ask any drummer. Just a thought.

If your looking to isolate a TT especially with spiked feet, I've been experimenting with 1" thick plate of aluminuim braced on the bottom with cross bars of 3/4" square aluminuim. I've had some great results so far as a top to DIY sandboxes. A couple of manufactors will cut plate aluminuim to size for you. A 20x24" plate 1" thick cost me about $200 delivered to my door.

Sorry to not answer the thread question. I really do not know about the brass.
