What's under your bookshelf speakers?


I recently picked up a pair of ProAc Tablette Reference 8 Signatures in bird's eye maple for my office system. I would like to protect the finish on the bottom, but also preserve/enhance the sonics. At the same time, seeing as how this is in my office, I would like to keep things visually discrete. Currently, I have a small mouse pad underneath each one, and in truth, this seems like it might be a viable option. However, I haven't tried them with another product underneath them or with nothing underneath (don't want to damage the finish), so I am not sure what sonic effects the mouse pads are having. The system sounds pretty good as is, though.

Thanks, Tom.

Mapleshade records recommends spikes to de couple the speaker from the stand. As a last resource use wood plugs which are better than any soft material. Best thing about all these suggestions is that they are not costly.
I can also vouch for cork...which can be found in smaller "panels"...and which has a harder density fiber board on the back...these were often used to assembly cork wallpaper...which I had as a kid...and is much more durable,affordable, etc. than thicker slabs of pure cork(the cork is actually only on one side)...and to my ears doesnt "deaden" the sound as much...good luck...
If damaging the finish on your speakers is an issue, be careful with the Isoblocks. I've used a set in the past and, while they do provide good isolation, the black rubber left unremovable marks on both the bottoms of the speakers and a hardwood floor.

With any soft compound like the Isoblocks or the sorbothane pads I recommended above, you'll need to put something between the pads and the speaker. Saran Wrap works, or any thin plastic like that.
Thanks for the tip. I've had problems with vibrapods but didn't anticipate it with the isoblocks.
