Nobsound springs - load range

Imagine now fine tuned  damped loaded speakers with springs asymmetrically compressed  under and over the speakers....

😉

@noromance brilliant 😂

@mahgister I am realizing how much I don’t know. How deep does this rabbit hole go?

I am like you, i dont know either...

It is just fun to create simple experiments...

Merry christmast to you....

@mahgister Merry Christmas to you!

Let's see, so we can put springs under the load, and also attach springs to the ceiling, with an adjustable rod attaching to the top of the load. Yes, a good weekend project, for sure.

I decided to give the Nobsound springs a try with my MC275 amplifiers. They were already resting on oak plywood bases (home made). I removed the feet and placed the bases on the springs and made sure it was level. Hooked everything back up, started my system and starting streaming the song "Along in Kyoto" by the group Air. First song and I heard details that I had never heard (maybe noticed) before.

I am trying to be skeptical about this, but the next album I streamed had what I can only describe as more depth. It was as if the sound field had depth below the floor. It’s a strange description, but as I was listening it was as if the floor dropped due to the sound field. It’s a weird sensation. It is really difficult to describe.

Instant success with first installation? What luck! I failed in my first attempt as the sound got worse when I first installed the Nobsounds. It took me about 5 days with arduous trials to get to the optimal spring configuration.

Now take a piece of 1-1.5" all-thread and drill a hole in the top and the bottom of the speaker, countersink the holes top and bottom and use 6" x 1/2" washers. Now tighten to tone. You can make the cabinet sound like green concrete, if you tighten correctly.. Cost a couple of peanuts at least, all thread ain't cheap.100.00 should do it, used would work, 30-50.00 for 2 pieces of 60" all thread and make the washers.

Master M, you’ve done it again. :-)

Enjoy the holidays..

I finally got around to taking my Emerald Physics 3.4s off the Harbor Freight dollys they've been on since I got them over a year ago. Each base is resting on 4 full spring Nobsounds. Quite an improvement!

Good to hear @tweak1 . What improvement have you experienced?

I was just lucky. I think the quick success might be because I have tube amps (microphonics). Also, the amps sit next to my speakers (mono-blocks) and I know they pick up vibration. I have picked up two more sets of springs. One set will go under my tube preamp and the other will go under my turntable. I just need to make two more isolation platforms (sandwiched oak plywood) for both components.

richer tone from top to bottom, especially in the lower mids and bass

Also due to the added height of the dollys the sweet spot was too high, now where it was intended

@noromance 

I just got a set of the Nobsound springs and there’s no instructions at all. So I have two questions. First, my Hegel weighs about 44 pounds. Is 4 springs enough or should I use 5? And the second is, should I put them under the Hegel’s feet or next to them?

I’ve read most of this thread and the answers to the first question varied a lot and the pictures I saw had people doing both.

Thanks in advance.

@noromance 

I just thought of another question. I have a bamboo cutting board. Would it be better to put the four Nobsound springs under the cutting board and the put the Hegel on top?

Thanks again.

I use Nobsound springs under the existing feet. But, only way to be sure on your system is to try.

Four Nobsprings are plenty for 40 pounds. I would remove enough springs for them to compress about half way when loaded.

If I chose to use a cutting board, it would be under the springs and separated from the shelf by vibripods or other elastomer disks. This gives another layer of isolation. I am doing something like this using a Black Diamond Racing platform and springs on top and vibrapods under. I would not couple all the springs together… and most components are heavier in back. Best to tune the springs to each location.

@curiousjim Hi Jim. Put them under the component not under the feet. I tried it once and didn’t like it. But I use tubes. However, @ghdprentice found that it worked. Use the necessary number of springs for each of the 3 points under the component so that the component is level after the set up. Obviously, use 4 under speakers. I can’t state it clearly enough - try difference configurations by listening. e.g. try it at 20% and 50% compression, under feet or chassis, 3 vs 4 etc.

Thanks @noromance ​​@ghdprentice 

Today I set up the springs with 5 in each and put them under the feet on the Hegel and listened for a few hours. Tomorrow I’ll move them off the feet and give them a few hours.

Oops. My bad. I moved mine from under feet to under the chassis. Sounds better. Not sure what made me initially put them under the feet. I have used, cones, vibrapods, pucks…. Long list and never put them under the feet. 

Oh well… senior moment when I did that.
 

@ghdprentice  Thanks for confirming.

My speakers (Reference 3A Nefes) are about 160 Lbs. Any ideas on how to increase the weight capacity of the 4 Nobsound Springs so I can use them? At $1,000 for 8, the Gaia I footers are not an option.

Oh, I also thought about using 2 in each speaker corner. Would that do the trick?

Thanks

My suggestion was going to be just use more Nobsounds. I guess you could search out different springs/load rating.
