Skylan speakers stands-how much sand?

Thank you for the replies.

The tops are cut the exact dimensions of the Spendors.

The bass is good, but I can't tell about the high end. I really packed the sand in. Maybe that makes a difference, but I don't think it should.

The stands are very well made and very nice looking. Who would have thought that PVC pipe could look so good?

I replaced the speakers in exactly the same position. (my wife has never been keen about the blue masking tape on the floor.) I will continue listening to them, but there is definitely a difference. I agree that the low end is better, but I really think that they have lost a little presence in the midrange and top.

They still sound good, and I like the stands. They are infinitely better than the metal stands that I was using.

I don't know whether there is a solid connection between the stands and speakers, but I can feel the low end vibrations in the stands. I have hardwood floors and am not using the carpet spikes. The adjustable feet have flat metal bottoms.

Thank you very much. Those threads are very helpful. The stands came with flat metal feet, about .5 inch in diameter. I think that I will get the Isonode footers and the big dots.

Thank you, everyone.

That did the trick!

I placed Herbie's small Fat Dots under the speakers (Spendor S3/5), Herbie's self-adhesive grungebusters on the Skylan speaker stands' .5" flat metal feet, and Herbie's self-adhesive grungebuster Extra-Thick Minidots under the audio rack's spikes' floor disks. (I used the self-adhesive grungebusters on the feet because I need to move the speakers when I am not listening to them to prevent my young children from knocking them over.)

The Fat Dots substantially reduced the vibration in the stands. I assume that the grungebusters on the speaker stands' feet also reduced vibration in the floor.

The low end is even tighter than when I loaded the stands with sand, and the mid-range and high end are back.

Excellent! Thank you, thank you, thank you!
