toddverrone,
I saw your picture of the padding. Very similar to non-slip kitchen cabinet mats or tool box padding. Nice.
I've quit following this thread.
Good luck & happy listening!
|
.... that may work. A drill w/ a round sanding bit? Since only three areas are of interest, precision is not a major factor.
The wood on wood, I think, would be a better alternative to wood to carpet padding, as you've already written...?
Happy listening.
|
now (that's) funny!!!!!!!!!
|
you ain't going to get this (stuff) from the magazines!!!!
|
..just wondering..instead of the carpet padding under your wooden balls... have you considered maybe a wooden coaster (as in a drink coaster)?
Anyhow... You are on the right track. Thank you for posting, in more detail, your experience!
Happy listening.

toddverrone,
Thank you for explaining your current changes. More importantly, how those changes affected your listening experience. This is what (it's) all about. Not (who) provides the info that leads to the changes, it's (the affirmation of the info and how it's affecting the change).
I'm glad you are enjoying a positive listening experience based upon the info you received from (all) involved with this thread!
Happy listening!

miner42,
I'm seriously considering posting my system on a virtual page just as a template..as I have most of your issues that I've overcomed!
|
13blm,
Your post last post should had been your initial post. I totally agree with you here.
stringreen,
You're coming from this by not considering the suspended floor aspect. From what I've seen on your virtual system page (last time I looked, 3 years ago?) you have a system that doesn't take the challenges the OP faces?

"too wobbly".....
I have my 2 tier audio rack that I use for my 50lb. amp and my Hydra, along with my maple platforms, BRD shelves... lots of weight.... between my speakers in my small listening room.
My bottom maple platform (3") is coupled to my suspended floor by 3 carpet piercing brass feet screwed directly into this platform. Above it are four SUPER STIFF SPRINGS into another maple platform (1 & 1/2") thick.
My rack and components sit on top of this. When I walk by, I can see the whole (thing) move. The components, however, are isolated. The sound I heard after doing this was/is transformative!. Wobbly? It can be a good thing.
"too wobbly" doesn't address how this sounded in your set-up.
|
toddverrone,
I read on another thread about your using wooded balls under your Rega after I posted on this thread. I may have gotten the time line wrong. If so, my apologies.
|
handymann,
Yes, room treatments do wonders in providing excellent bass response while also taming bass room nodes.
toddveronne,
Sorry. I guess the lack of the OP responding got my juices flowing..
Your thanks to the OP, while relevant, are ultimately misplaced. The thanks for the gain you've achieved through the OP's posting should go to all who have provided the info.
Your use of three springs, "too wobbly when I tested it". What/how did this translate into the sound???
miner42,
You never responded as to your "audio console". When I read that term, I envision an enclosed structure? Given all of the problems you need to overcome, IMO, having an enclosed audio console in the center of your speakers on a second floor is quite a lot to overcome? I do realize it's not relevant now?
Given the changes you've made, I'd say it's time for some quality bass control. I've had great success with the Vicoustic Extreme Bass Panels.
"Woofer pumping during tt usage", again a sign of the tt isolation being ineffective.
|
Thank you for your honest response.
Sorry to say that after all of the info I/we provided.some like toddverone chose to post their resulting info on another thread.
The OP never responded.... Toddverrone took the info and ran somewhere else.
I'm not getting a good vibe???
Sorry I took the time.
|
lewm,
My thoughts exactly.
13blm,
Not to get into a debate, but I've heard the difference in my own system of various aftermarket cones, stillpoints etc... Saying they do nothing for isolation is just plain wrong in my experience. Maybe we could get into the symantics of isolation vs. effective ways of dealing with
vibrations/resonances but I won't do that. I just report on my experiences.
Good luck with your products!
|
(I use these types of things on the platform and not the component itself.)
bdp24, You're absolutely correct. Sand is very inexpensive as well!
Geoffkait, Thanks for allowing me to explain my process more than I initially did. I have a new DIY wall mount/equipment platform I'm completing in (my mind). I will be ordering more of your springs in order to make it a reality.
Happy listening
|
geoffkait,
I understand where you're coming from. I know that lead can deaden the sound if not used thoughtfully. I should have then said, the shelf that supports the component I need the additional weight in my system to get the proper loading, I use a BDR shelf that doesn't react to the addition of lead like other materials. I have several weights of brass with points that work well in other areas.
My main point was, for a tt, where level is critical, I find in my system, I like to have a support structure that has a built in leveling adjustment. I find if one has a tt with adjustable feet, it's best with them screwed all the way in and do the leveling elsewhere. In some cases where finances are a major factor, this may be a way to go at some later point. Another positive is that you can then play with better (feet options) on your tt that will better address the sound quality while still using the springs under a tt's DIY shelf.
Having said that, the addition of marble shelves or any other shelves, while adjusting for load, will not help with the leveling. The bags of lead shot or brass feet strategically placed is an option that can kill two birds with one stone, so to speak.
The important thing is to get started and all of the many options available to you will be a good upgrade in the future.
|
I use different sizes/weights of bags filled with lead shot to match the load when needed.
|
There is also the issue of leveling...especially for a tt. You can find the "sweet spot" if you don't have a base structure that has the ability to adjust level.
|
toddverrone,
Once you figure out the weight of your Rega and wooden plinth, you'll have another decision to make, IMO.
The standard thought would be to go with 4 springs suited to the weight of your equipment. Here's another thought...what about three springs? Depending on the weight, 3 springs will give you a somewhat horizontal isolation effect in addition to the vertical because it won't be as stable as a 4 spring approach. Of coarse you can buy four and try each way. You won't be out much money. Food for thought?
Later, you can try cones under your wooden plinth as well/and/or some sort of discs under the springs. I use carbon fiber discs at some locations, dependent upon the final sound. Lots of options.
|
toddverrone,
Could you expand on what your application for "springs" is for, etc?
|
dlcockrum,
Thanks for the laugh! ( of coarse I meant (3) decades). I'm glad all of you are willing to put up with me, most of the time.
Happy listening.

I wanted to tell miner42 that, while he had the upgraded feet for his tt, that in it's center is rubber! That is what connects, (forget that) Traps! the resonances by not allowing a freeflow of these vibrations!
Rubber is not your friend!
This is certainly not his main concern. It is, a valid point.
There, I said it.
|
@toddverrone,
I cannot think of ANY area of isolation in my 30 + decades in audio where rubber (innertube) doesn't degrade the joy of listening!
Forget about the idea of the whether maple or teak is the culprit. It is the RUBBER!
Happy listening!
|
miner42,
Try replacing your marble for inexpensive MDF. I suspect you'll notice a difference.
This won't solve all of your sources of problems but will validate in a minor way what we've been saying.
Happy listening
|
@bdp24,
This may be an optimum platform to try your future plan?
I can provide some pics if you want?
Happy listening

1'8" = meant to write 1/8".
|
You both may find this of interest..
I've fabricated a 3" maple platform that I've recessed 3 Symposium jr. (cups) into (flush) w/ the top of the platform.....on the bottom, I've a 1'8" recess for my Super Stiff Springs.
An effective,versatile platform that can be used in various applications.
I'm currently using it in my similarly modded rack that my amp/conditioner rests on.
|
@bdp24, @toddverrone,
FIM made a ball n" cup device as well that was priced lower than the Symposium jr. Maybe still in production???
I almost offered one of my Symposium jr. sets up for sale, thought about it and decided to keep.
They were offered w/ two levels of ball bearings, one of harder strength. (Tungsten)??
I took it one level further and acquired ceramic balls. My project at this time was my VPI HW-19 mk IV that i"d taken way out of stock.
The ceramic ball bearings were a step up in this particular setting, adding major transparency... the highly resonant plinth/base of the VPI was HARD to overcome!

ct0517,
I think we are on the same page. This has been my personal experience.
I hope we hear from the OP? It is now up to him.
Happy listening.
|
If you haven't already watched the Townshend Audio YouTube video showing how a speaker on a concrete floor reacts to vibrations, you should. (bdp24 has talked about this in other threads).
Then think about if a speaker on a concrete floor has this much vulnerability to vibrations, surely your tt on a second story will be magnified multiple times over.
Food for thought.
|
miner42,
Did you ever try ct0517's dance tip? If you are embarrassed to dance, follow his directions without the dance. If you're getting the low frequency noise this way, something in your tt isolation chain is not set-up right or is not able to isolate effectively for your particular situation.
What type of audio console are you using?
|
I use machina dynamica super stiff springs between my tt platform and my wall mount. This is an inexpensive option that works very well.
