Thoughts on Turntables and Vibration

FishStalkerGuy said:
When I had my Nottingham turntable, I bought a wall mount that I screwed into wall studs. Had to use a good size lag to hold the weight but it fixed the vibration problem.

This is exactly what I have done in multiple rooms. Wall mounting, particularly if you can get a load bearing wall, solves most macro-vibrational issues like footfall concerns and gross distortions. Beyond that, it is trial and error to find the best solution for your particular situation.

I've never seen it done, but it should be practical. Something similar to a projector hushbox but with more significant acoustic absorption and no gaps when the door/lid is closed. Pre-made, you could maybe go with a home recording booth for a few thousand dollars, most of which would be large enough to accommodate your entire turntable setup. Maybe add a bit more absorption for the mid-bass and bass frequencies if needed. The cables could thread through a hole that is airtight.

I suppose you could go even more extreme and add a vacuum pump system to remove any air inside during playback, and then to let air back in when you need to open it. Some sound isolation units are already designed to connect ductwork to them.

The most I know of someone doing is cutting a hole into their floor in order to mount their turntable on a pole going straight into the ground, completely decoupling it from their house.

I thought this was a joke at first, but now I think you’re serious.
 
I don’t have vibration issues such as vibration due to footsteps. Again, I only experienced the vibration when I played the music very very loud. I very rarely listen to music at that volume and when I do, it is only for one song or two max.
What I was asking if any of you have experienced something similar when playing rock music at that high volume (100-105db)

I definitely have. Permanently solved by wall mounting. Deep bass tracks played loudly would literally cause the stylus to jump out of the groove (and this was with isolation under the table). Wall mounting on a load bearing wall was the only solution I found that worked. I could then play music as loud as I wanted and could jump up and down in front of the turntable with no issues at all. I have replicated this in my current room on a non-load bearing wall and it seems to be working equally well.

Have you guys tried to play very loud music (say rock at 100-105db) when your turntable is in the same room as your speakers?

At normal listening levels I do not hear or notice any induced vibration. But at those levels I do.

Many years ago, I used to have my TT in an adjacent room and never experienced such a thing.

It makes me wonder if having a TT in the same room as the speakers is a compromise. Even if one is using some kind of isolation, I’m thinking that you can’t stop the sound wave from hitting the turntable directly bypassing the isolation system. Thoughts?

What TT, i used to have those issues only with DD tables mostly Technics 1200 ..

VPI Classic with the tone arm that comes with it and a Benz Micro.

What type of platter mat are you using .?


Suspended tables are best for that kind of listening , technically speaking all TT’s have to be suspended in some form or the other to reduce these harmonics, if not massively built that is ..

Simply because it makes listening to an LP at that level impossible. That’s why. I wanted to play the LP but ended up switching to digital with no vibration issues. Make it another point for digital.

Another point for digital, not really , CDP’s will skip too ...!

No need to apologize, its your system and ears , dont let the i cant crank it up because its clipping db Police kill your fun ..

I’ve got a high moving mass (22 kg) Nottingham Dais and can play plenty loud without issue. My table is not near any room boundaries and 6’ away from the nearest speaker.

I don't really think someone should go that far, but they theoretically could. :) However given what people are willing to invest in their systems, I don't think the cost or effort required is that horrible if they need a solution.
 
my system is in my family room and has a suspended joist floor. i put 3 jack posts in my basement that is below my family room. one under my turntable stand and one under each speaker at the closes joist. this worked great, i have a Linn LP 12 which is know for foot fall issues and i have no problems of any sort at all. john
 
I once had my TT suspended from a wall but never played it that loud since I was living in an apartment.
I also once had my TT in another room separate from the speakers and I played my LPs very loud without issues..

But now have my turntable and my speakers in the same room and I cannot play rock music at 100-105db without experiencing vibrations from the TT.

There are free apps that you can download on your phone that let you measure the actual db level in your room.

Any one of you with a TT can check out their experience and report back.
 
Many moons ago I had my TT on a shelf that was screwed into the wall studs, it was not a load bearing wall. When I turned up the volume it was horrible. I wound up making a square shelf to put the table on, mounted 4 eye hooks in the ceiling (into the joists) and hung the shelf and table on 4 springs and chain I got at home depot. It worked like a charm. Good luck.

Hi Nico,

I'm trying to follow the progression of this thread after becoming aware of its existence from a friend. Are you interested in possible solutions or are you just wanting someone to report back on their findings listening at 100-105dB (peaks?) or both?

If you are looking for possible solutions, can you provide a bit more information? Here are a few practical question I'd ask:

- For a practical application test scenario, can you list a couple of rock LPs (hopefully something I have in my archive) and track titles where you have experienced this issue so I can attempt to duplicate?

- Can you explain the type vibrations you are talking about (This would be something like: a type of feedback that overloads the system and creates severe distortion or something else explained in a similar manor.)

- Can you share the condition (or scenario) of one or more of your LPs where, within the music's performance, this occurs. (for example: 2:34 into LP xx track title xx, the vibrational feedback occurs, etc.)

- If you listen to the same music at the same level setting on your preamp and you turn your subwoofers off, do you still get the same condition? (I'm not suggesting you stop using your sub. It's just a test case that could help provide additional information to help with identifying the effect under a different condition.)

- Are you on a concrete or suspended floor?

- What type of support (equipment rack, platforms, feet, etc.) do you have for your turntable?

- Does your phonostage contain vacuum tubes?

If you'd like to, or prefer to, discuss this offline, we can arrange that. We have a mutual friend that once lived in R. Va. when we first met many years ago. If your contact info hasn't changed, it is available to me. If it has changed, you can contact AC and ask him to send you my contact info.

Per your advice and that of others, I broke down and acquired a BM-8 for my Simon Yorke S10. I really had no choice since the Yorke is suspension-less and high mass. Im renting a house for now and the system resides on the 2nd level, footfalls were making vinyl replay well nigh impossible. I have a second SYD table on a wall shelf and its fairly immune from feedback and an interesting contrast, comparing two near-identical 'tables with different isolation solutions. I'll save you from speculating, the Minus-K was worth every cent and I got the nickel tour of the factory to boot.

Rob,

I'm happy to read that the suggestions from myself and others about looking into the Minus K platform was helpful. That's an excellent outcome for you and one couldn't ask for more. Thanks for sharing your situation. For those type of specific applications, the Minus K is highly effective at accomplishing the desired results, in my experience.
