I had the cones under a component and also under a pair of older Kharma speakers. Wasnt much of a fan. I agree with geof in that I think the shape was wrong for many applications. I have never found a one size fits all solution in this realm, however.

I received an email from Music Direct a couple weeks ago offering the BDR shelves again. Anyone else notice this? I use them extensively in my system and actually use carbon fiber sheets in DIY projects. I'm a big fan of CF's usefulness in audio.
