Hello, Herbie. I am quite happy with the sonic improvements that come from using the giant cone/decoupling gliders under the Soundocity outriggers on my Genesis 6.1 speakers. I was able to play with the setup for about 2 weeks but then had to take my system down while the rest of the remodeling project continues. With luck, the carpeting will go in next week and I can begin to put it all back together on the best wall for the 2 channel rig.
With the end of redecorating in sight, I will no longer have the built-in dining room hutch for my components and will have to make do with a new 3-shelf super-wide rack from Steve Blinn. While going over the assembly instructions, it occurs to me that the best time to tweak it is before it is put into service. I will soon be ordering 4 more gliders to put beneath its cones, but I think it could use a bit more TLC. The rack consists of 3 nicely finished 50 lb. maple shelves supported by aluminum box-channel extrusions that ultimately offer up 8 1/2" rubber hemispheres that pop into holes formed in aluminum supports that are bolted, 8 per level, to the horizontal frame members. These supports are each 7/8" x 1.5". These little half-balls look, feel, and smell like rubber, and I think they need to be replaced right away. The heaviest shelf when loaded, will be about 320lb, including its 50 for the shelf. This means each mini-support will bear about 40 lbs. What do you suggest? FWIW, the other 2 shelves will be loaded with only about 100 - 125 lb and so may be able to donate some of their supports so that the heavy shelf has more points of contact.
Thanks for your help,
