Hi,
I had my speakers (VMPS 626 Ribbon Monitors) on top of granite blocks 12" x 12" x 16" high.
I also noticed a slight tightening of the bass, but I think it went down as deep. Ultimately, what I think I eliminated was floor resonances.
One other thought, may work even better: try a vinration draining platform under the speaker, with and without the granite slabs. I got a pair of Resolution Audio platforms and they did very nice things. I now use them between the blocks and speakers, and they're not moving.
I think the granite slabs give the speakers the stiffness as a good stand, but the vibrations may end up going back into the box, and this can color the sound. The A-R platforms, like the Symposiums, drain the energy away fromt he cabinet.
See if you can borrow soem Symposiums if you have a local dealer, or look at www.audio-resolution.com; FYI, I own 4 A-R platforms, am VERY pleased with them, and wrote a review on Audiogon, check it out.
Much luck !
