Is anyone using sand boxes under their speakers ?

I had a pair of Brightstar's BigRocks under my Dynaudio Contour 5.4's for quite awhile, but then found better use for them, one under my turntable, the other under my uni-disc player, where they actually made a discernable difference. At least in my situation, yours may vary. Solid maple risers would be just as, or more expensive than the BigRock's. I've heard of folks using solid Granite with excellent results claimed. Maybe you can do some experiments using different materials to see what works best.

Good luck,
Dan

I would consider a Sistrum Stand. The SP-1 would raise the speaker up maybe 4 inches (check thier site or Talk with Robert, who can assemble the size cones you'd need.

The sound quality will most likely improve as well.

Damn you Timtim! Now I have another DIY project to schedule.
Seriously though, I raised my speakers up a nearly 3 inches with some plinths made from MDF, spiked to the floor with sorbothane pads on top. The results with both Thiel CS-1.6s and Meadowlark Audio Kestrels was very positive.

I raised my Hales Rev 3s using concrete pavers (12" x 12") which I painted black. Under each are four hockey pucks. The Hales with spikes sit on top. Not only did i raise them up where I wanted, the bass response tightened up as well. And the cost was well... cheap.
