Cheap Speaker "Isolation" Solution for 300 lb. Speaker


 Good Afternoon All,

I am looking for advice on a cheap and simple isolation solution for large, heavy (325 lb. each) floorstanding speakers. 

I've read much advice on granite or marble slabs, multiple layers of cork, springs, etc; while this has been helpful, it is neither a cheap or simple solution. 

Ultimately, I am looking to protect my wood floor from damage these very heavy speakers might do, as well as decouple the speaker from the floor in order to reduce bass resonance (I am in an apartment complex and worry about noise complaints). I've looked into sorbothane pads, but they never seem to be able to hold this much weight.

Thanks!

The dampers from teo audio are world class. Big time. Put them up against anything, in a technical and test oriented set up, and in a sound quality test, and they will win out in all ways and areas of testing.

Go ahead, call me on it. Test them to your hearts content. Good luck with that. :)

When one of those pads is loaded with about 45lb per square inch, that is just perfect ...and it acts like 2hz damped spring/buckling isolator.

I can take one and drop it on its edge and it will bounce like crazy. When I drop it flat... it just goes ’splat!’ and stops. I can make a video to illustrate.

In the earliest example of their use...Mark Doehmann of continuum (at the time) had a chance to play with them when their turntable was first introduced at the NYC show.... and he thought they were pretty dang special.

If people want we can have people pay $500 for them by adding the jewelry part and hiding the damping material inside... but that would be less than honest in my book.
You can try these Pads can are good up to 60 lbs per square inch. thats 960 lbs per individual pad. 4 PACK ANTI VIBRATION PADS ISOLATION DAMPENER SUPER HEAVY DUTY BLUE 4x4x7/8 | eBay I have used these under speakers and to also isolate my TT
free shipping also 2 packs should be enough for both speakers at a cost of $26.00
alucard19, the price is certainly right on those pads! For that price, can't hurt to try em. Not high on the physical appeal value, but function is function. 

The Gaia line of isolators looks great but I just cannot justify spending that kind of money for isolation feet, regardless of how effective they are. I just don't have the budget for it. 

The Teo Audio diamond isolators don't exactly look robust, but the description certainly fits the bill, as I absolutely need the bass dampening considering my apartment situation. The site doesn't describe much though, I can't find info on the max load weight per pad or the price on these. 


I'm using 2 inch thick slate slabs on top of hockey pucks for my Monitor Audio PL300II's and works great. If your looking at stone I recommend slate, which I have read is the best for sound resonance, as opposed to Marble and Granite which are not very good. 
I know you are gonna laugh BUT: for isolation under my 85lb speakers (Gershman Avant Garde RX-20), I am using tennis balls inside Tropicana Orange Juice bottle tops! - 4 per speaker (one in each corner). As long as your speaker bottoms are flat - for your speaker weight - I'd experiment with a muffin tin (12slots) with new tennis balls (colors your choice). Your speakers will look like they are on something Post-Modern, designed for a Portland Oregon municipal building in the 90's...
I am sure that die-hard long time audiophiles - wordsmiths all - who contribute one-liners or tomes, should bring a chuckle in reply to my suggestion... But it works for me.
Good Luck to you - and don't be afraid to experiment...
