I have a much better idea that's works far better. I have gone down this road you are on and this next option works far better.
Get some Star Sound Sistrum platforms under your speakers and you will be amazed at the results. They come up used and work wonderfully.
The granite thing may look cool but the results are not as good. Sistrum improves focus, detail, separation of instruments, cures muddy bass lines, and let's the music flow out with improved clarity and fidelity.
They would be ideal under your speakers. I think the smaller 03 or 04's would fit. The larger SP1's may also work. Just look up the dimensions.
The granite did tighten up the bass, but did not do the other things mentioned above as well.
