Granite Slabs


I recently put granite slabs under my Paradigm Studio 100..the sound is not worse then before if not better..my wife listened;she said the bass is tighter..slightly..but when I listen to it I feel like I lost some bass..or I feel as if the speakers don't rock as much as they used to before..or I am mistaken???..I don't know..can you help me??I would like to hear your experience with marble or granite under the speakers..did I really lose bass??(my ground is wooden..I used to have small carpets under each speaker before..now I have the slabs)

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 !

Your wife is probably on the dot. From your description it looks like you CLEARED the bass. What you were hearing before was a muddy low-end that contained distortion -- and sounded loud. Your mention of a wooden floor strengthens this impression. Stay with the granite -- maybe even adding spikes b/ween speakers & granite! Cheers
I agree with Gregm.

I did marble slabs under my speakers and the bass and soundstage improved. Additionally it seems to have made the definition of instruments better and less muddled or as gregm says CLEARED.
