Isoacoustics overweight

How many helium balloons would you need to lift the extra pounds?

I had the same issue with my speakers. I was looking at the first version supporting up to 220lbs, my speakers 275lbs each. Called the company to see if they would take the weight of my speakers. Too heavy but there is some room for greater weight and you should be fine at 125 lbs. I ended up purchasing the lower model of titan series supporting around 320lbs. I think you will really like the product. Best wishes. D

Have you tried SET? Couple months on a low-watt diet those speakers will drop 20 lbs easy.

Twoleftears has correctly read and economically answered the OP question.  Bravo for staying on track and providing a useful accurate response, sans hyperbole or off subject pontification.  Refreshing.
