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!

Not cheap, I used Gaia l on my Joseph Audio Pearl 20/20. Well made product that really does isolate. I have pine floors throughout my cabin. They have rubber (almost like suction cups) on the bottoms. I have outriggers, so after running them through the threaded outrigger, I finished the top with a stainless steel acorn nut. They really tightened up the base. 30k plus speakers (they are great speakers) and they only come with spikes! Insane! I payed 1200.00 from Crutchfield for the Gaia I, I hope this helps? |
Herbies, or something along these lines: https://vibrasystems.com/cork-neoprene-pad.html |
There are appliance dollys that might work for you.They are available in many sizes,wood,plastic,or metal.https://www.googleadservices.com/pagead/aclk?sa=L&ai=DChcSEwjll8am4_HmAhWChsAKHRVJDf0YABAdGgJpbQ... |
Seems to me that one of the simplest, easiest, and relatively cost-effective solutions to what you’re looking to accomplish would be Herbies Giant Fat Gliders. If those alone don’t provide enough isolation, maybe consider adding Black Diamond Racing Jumbo Pit between Gliders and your speakers. Just a crazy thought. |
I agree with you, Geoff; beyond the complexity of building such a support for such large speakers, I'd have fears over their stability. The washing machine anti-vibration pads seem like a genius idea. They sure would be able to hold the weight, and while I'm not entirely sure what their impact on the sound will be, it's worth a try at the cheap price! |
The problem you face with springs is the same old problem - the springs need to be widely spaced, so that means you would need some structure to allow the springs to be placed in a wide pattern, pattern outside the dimensions of the speaker footprint. Otherwise the speakers will topple over. It is feasible to construct a large 3x3 CROSS that the speakers sit on with springs of the correct stiffness under the CROSS at each of the 4 corners. Tricky but feasible. That’s a DIY Townshend Podium. But something that heavy is dangerous on any support IMHO. |
Sorbothane can easily support this weight, it is just a matter of choosing the right hardness of Sorbothane and the right total surface area of the Sorbothane. Springs are easy as well, again, just need to pick them correctly. It is easier to get a low resonant frequency with a spring to cut-off all higher frequencies. There is another thread running now about DIY platforms with a lot of ongoing "discussion" about springs, sorbothane, etc. |
wspohn, That's a good suggestion. I've see a lot of debate regarding the spikes + discs combination and whether it couples the speaker to the floor or decouples it; I can't say I know enough to confirm it either way, but I certainly could use help with positioning such large speakers and it sounds like wheels would do the trick. Thank you. |
