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.

A very similar product to what Mijknarf suggests is a rubberized shelf/drawer liner that you can buy anywhere - Walmart for instance. Comes in a few different colors (not that you'll see it under the speakers) and in much smaller sizes than the product for area rugs.
I'm glad I asked this question! These are some very innovative ideas!

Thanks, Tom.
Like spikes on large floor standing speakers, the idea is to decouple the speakers from floor or stands. So any "soft" materials will have absorbing effect and slightly smear the mid and bass definition, if you can hear it.

Hard material is better, but they will scratch the nice finish of speakers. I will recommend BDR cones which has rounded tip and will not damage the surface. Problem is they are slippery and speakers can "fall off" from the cones. That has happened to mine, cost a lot more to repair the speakers when damage is on top than some minor dents or scratches on the bottom of speakers.
