marksdad Posted September 24, 2003 Share Posted September 24, 2003 ok guys, i have not yet decided on an pre for my tt, i am actually having trouble finding any to audition, but that is not the prob. my current problem is that i noticed that my turntable shakes quite a bit just walking around it, after reading a few articles about placement, i read that my current placement (high atop my audio reck) is the worst place to put it. i lkie where it is at for the show off factor, but for actusal playback i am afraid it wont work. my idea is to either build or buy a rack for just the tt, my problem is room, i am now very limited due to the size of my heritage gear, i want to build a small table to fit in front of 1 of my cornerhorns, since this should not interfere with and sound output, and the output should not interfere with tt play, if i can get my camera working (new) than i will send photos to help your imaginations, thanks in advance Quote Link to comment Share on other sites More sharing options...

Deang Posted September 24, 2003 Share Posted September 24, 2003 If your rack shakes just from walking around it -- then I wouldn't just be worried about the TT. How much gear do you have, and what is this rack you are using now? Quote Link to comment Share on other sites More sharing options...
Mallette Posted September 24, 2003 Share Posted September 24, 2003 Dean: Could be a pier and beam floor. Never had one that didn't require battening down the tt. As to TT stands, my favorite budget stand is a simple wood box of the right height, filled with sandbags, gravel, or whatever to ballast. You can kick one and your record won't skip. You can build it or look around at furniture stores for pedestals and such...but make sure whatever it is is strong enough to handle the weight.

mobile homeless Posted September 24, 2003 Share Posted September 24, 2003 I wouldnt put the rack next/front of the Khorn for a variety of reasons. One, the vibration and two, you are blocking the speaker with an object that is not present on the other side. The stand you make or buy depends on the table. High mass, heavy stands are BAD with the Linn LP-12 and good with other tables. Light, extremely rigid stands are better for the Linn. There are a number of options, directions you could go. Is this the only place you can put it? A good stand is critical for all your gear but the MOST important with source components, especially the turntable. kh Quote Link to comment Share on other sites More sharing options...
T2K Posted September 24, 2003 Share Posted September 24, 2003 Put it on the workbench in your garage. That's where it will end up anyway. Hope this helps. Keith Quote Link to comment Share on other sites More sharing options...
Klipschfoot Posted September 24, 2003 Share Posted September 24, 2003 In addition to any other tweaks, if you can, put the "rack" in the corner of load bearing walls to give it more support. It sounds like part of the problem could be barely-code floor joists. Do you have a nice rack? ;-) Even if it is made of tubular steel, it may always be problematic if the floor is springy. You could also consider a platform mounted to a load bearing wall. (WAF=0) Quote Link to comment Share on other sites More sharing options...
ygmn Posted September 24, 2003 Share Posted September 24, 2003 your rack should not move when you walk by....I would check to see why..... Is it the flooring being loose....or is it on carpet and you need spikes....or does the rack need mass...whateverit is fix that first..... Then check again.,....

LarryC Posted September 24, 2003 Share Posted September 24, 2003 Search for "Feedback" on the forum. A wall-mounted rack such as Target's worked well for me and the person who started that thread. Quote Link to comment Share on other sites More sharing options...
Colin Posted September 24, 2003 Share Posted September 24, 2003 You need a Vibration Isolation Platform (VIP). I rested a thirty pound gray paving stone on a 14 new yellow tennis balls to create my own vibration isolation platform and I did indeed notice a pleasurable change. Imagine setting a gallon of milk on top of a carton of eggs. Incongruous perhaps, but the result is solid and stabile - it does not shake or sway.

fini Posted September 24, 2003 Share Posted September 24, 2003 marksdad, I've got the same problem. Mine is due, as Mallett suggests, to a "post and beam" floor. My 2 channel set-up is in a "sunken" livingroom, the only part of the house with a floor stucture using 4X6's on 4-foot centers, with 1-1/8" plywood. I'm tempted to crawl under, in the moist adobe clay, to somehow stiffen the floor, but it's darn tight under there, and in an expansive soil such as adobe, piers need to be set on 6-10 foot deep caisons to keep from heaving in the wet Winter. I'll probably come up with something above-floor (i.e. stiffly anchoring the cabinet to the wall, like one might do for seismic purposes). If I were to design a house in this area with turntable stability in mind, I might pour a caison directly under the spot I planned on setting the turntable, possibly even pouring a concrete column up through the floor. What a plinth! fini Quote Link to comment Share on other sites More sharing options...

Mallette Posted September 24, 2003 Share Posted September 24, 2003 The old KWKH studios in Shreveport, LA were built in the 30's and had solid concrete TT bases a yard square. Talk about solid! Anyway, I still think the homemade box full of gravel is the cheapest solution that works and can be moved. Of course, cheap is me.

Soeren Basboell Posted September 24, 2003 Share Posted September 24, 2003 The best stand I have tried, is a well damped sandwich plate suspended in 3 nylon ropes from the ceiling - 4 ropes is also possible, but then the 2 of them must make a loop. It should be near a wall as the movements from the ceiling due to walking people are the smallest. The idea came when I was working with an old seismometer from the beginning of the former century, and it consisted basically of a mass of about a ton suspended in a spring. Thus this mass would rest in a stabilized position, while the earth around was trembling during earthquakes. I have always considered a turntable as a slightly modified seismometer. Another very fine and cheap solution is to place the tt in a room next to you. Peter Forsell did it with extremely good results, but you must of course have the necessary room(s) for it. A combination of the two ideas is a logic further step. Søren, back after a little break Quote Link to comment Share on other sites More sharing options...
marksdad Posted September 25, 2003 Author Share Posted September 25, 2003 as i drove to work i realized that i did forget to mention that the floor is like a springboard, as i walk through the house i can see everything shaking, if i shake my audio rack i can also see my tv shaking, and it sits on a rack all by itself, both are constructed of 1/8 tube steel, 1+3 inches in dimension, with 3/8's glass shelfs, very solid racks, in themselfs. i just cant do anything to shore up the floor, below me is a mechanical area. anyway the suspended idea is really great, i love it infact, actually i am intrigued by all of the ideas, you guys have put so many ideas in my head, the killer is what homeless & bkrop said, my space is limited due to the size of my ht, especially my speaks, this is why i considered placement in front of my khorns, i simply have no place to put them except there, it seems it is the least likely to pick up sound vibrations there, if i tried mounting wall or floor along any walls the bass extension from the cornerhorns would likely set up interference, it almost seems that i am doomed to sub par tt performance, or placing in the closet until i get rich and move, my experiences with tt as of yet have been very disapointing, when my tt arrived i coud see automatically that the sellor had the tt set up wrong, now i want to begin tweaking, but acording to the aformentioned link i need a battery of set up equipment, are the scales and associated set up tools really necessary? help??????????

Randy Bey Posted September 25, 2003 Share Posted September 25, 2003 If your floor is not stable, no stand will help. Consider a wall-mount unit, the pro units sell for hundreds but I think with some work and appropriate thought a DIY approach would cost a fraction of that. Otherwise, I am thinking myself of a stack of cement chimney liners, with a marble slab on top. No hurry though my flexyrack is supposed to be bad for tts, but the cement floor seems to help.
