I bought the Granite for the base for my ....

"base= bass. My bad. I am actually an educated person. I was thinking base as in the Granite base and had a brain fart.
Sorry about that."

Okay, I see. I did that (at least) once in a post also. I thought it was an intentional pun because of the smiley face at the end of your original post. That's why I responded with puns. (Puns are part of my "dark side.") My apologies as well.

The part about Lord of the Rings was true, however. It seemed ridiculously augmented. Quite odd, and sort of annoying too. You may want to see if the old 1970's movie, "Earthquake" (in "Sensaround"--remember that?) is readily available. It was actually possible to feel vibrations in the movie theater, and this was done at a time long before subwoofers were so popular.

I saw that with my dad in the theater. I seem to remember that speakers where actually added to the theater for that experience.

I remember something like that too. I think that's right. It was a long time ago. Anyway, if it's even available on DVD or VHS, it would be interesting to see how well a high end subwoofer would do with it.

I've had terrible results with granite as a base for HI-Fi equipment but if you must have it, the best thing to buy is a machinist base, designed for a tool maker / machine shop.

These cost a fraction of what similar materials sell for in the funeral business and audio business.

Here is an example of a precision machine base that's 9"X12" and weighs nearly 60 pounds, yet sells for only $22.00 because it's intended for tool rooms.

I went through this nearly 10 years ago, hope you have better results with stone than I did.

I will let you know Al.
