Where is Your Turntable?

Believe it or not, I once toyed with the idea of constructing a sliding track with a 3" maple base which would slide back and forth through the wall between my music room and the adjoining room. "In" to change the record and "out" when spinning. A sliding door in each room would be closed depending on current position. Maybe in another lifetime.

Veddy eeenteresting, thus far.

Patrick, I built my absorption paenl based on the Jon Risch recipe. I have pics of various contruction phases should you have interest. They're easily built.

Then, please, try harder. :-)

I posted this in another thread but it might be helpful in the context of this thread, too.

When attempting use of a wall mount rack, be careful before drilling holes and positioning other associated equipment (regardless of table). Room nodes can be an issue - a serious issue. I built a wall rack using 1000lb rated Stanley brackets and a 3" rock maple base. I positioned where I THOUGHT I'd be okay and attached straight into wall the studs using SIX 3" lag bolts. The floor was a poured concrete slab. As one increased gain, the air borne resonances caused a terrible rumbling mess. Touching the wall near the supports - rock solid, not so much as a trace of vibration. Further out on the base - different story. Moral? The rack can be mounted like a pillar and while you can eliminate floor vibrations and all but eliminate wall vibrations, those air borne forces are much greater than one would think. A two foot repositioning solved the issue entirely, but the six holes required filling and repainting in the process.

Does anyone know a way to eliminate this air-borne effect if someone were locked into an otherwise poor position for a wall mount without moving it elsewhere?

No, it is an outside, load-bearing wall with no perpendicular walls, though I understand your point. Built in the 50's it has 16" spaced studs AND angular bracing between studs (I know because I stripped off and replaced old knotty pine paneling!). So, wall vibrations were really not the issue in this case. Moving the rack 2 feet fully solved the issue, so I was always under the impression that air-borne vibrations were, indeed, the culprit. I can set a glass of water on the rack now at cranking volume, without so much as a ripple on the surface. I now use the wall rack for one table with two other tables sitting on sand-filled Osiris Giza amp stands. They all sound equally good, can't pinpoint any benefit of one placement over the other.

Hre in Clifrnia, tht can alwys b a pssble isu.
