Adjustable-height speaker stands--comments/recs?

Hi Drubin, you may want to check into Standesign #BB-75. They adjust from 30"-40" in height, have a 6"x6" top plate, and spiked bases. I actually use them for my HT in conjunction with 4 Sound Dynamics RTS-3s. They are really not a bad stand, although I don't know if I would be using them for any type of super critical listening.

I purchased mine at J&R Music in NYC for about $70.00 a pair although they are presently available from Audio Advisor for $65.00 a pair.

The base design will allow you to use some form of weighting if desired. For evaluation purposes, as you mentioned, you can probably get away with a couple bags of sand or shot, etc, laying across the bases. This will set the spikes adequately. Please keep in mind that this suggestion is simply for evaluation purposes only, and not something I would suggest as an end use product.

Best of luck.

Thanks everybody! The Usher stands have only a 10 cm adjustment, which is not enough. The Standesigns sound like the right idea (good price, too), but 30"-40" seems not quite right for the kinds of middle-sized speakers I want to try. Better would be something that adjusts from, say, 18"-32", but maybe that's not feasible.

Except for the price, they look like just the ticket. Thanks.
