Paul's explanation is entirely wrong

Paul McGowan: "I ask what it's supposed to be doing and got some long-winded story about a passive amplifier or some such. Mmmmm, no, methinks not. But here's what I do think is happening. It is a tuned "bell" if you will (it rings if struck) and I believe it is acting as a resonator that is being excited at specific frequencies we all find slightly edgy"

OK.

Paul McGowan: "As you put energy from the speakers into this device, its heavy mass simply absorbs that acoustic energy and reduces the peak of said energy."

Absolutely not. Mass doesn't "absorb" (dissipate) the acoustic energy. Something like that loses very little energy, it's reradiated back into the room.

"Its mass is such that it will not put the energy back into the room, thus acting like some sort of acoustic filter."

No.

I think it's a reverb plate. Well known that a little bit of tasteful reverb sounds nice.
