Isoacoustics overweight

Not exactly overweight, but I use GAIA 1s. Their max is 220 lbs and my speakers are 220 lbs. I recently contacted IsoAcoustics about their new Titan series and decided to stay with the 1s.

I wouldn’t hesitate to use the GAIA 2 supports. Doubtful 5 pounds will amount to a hill of beans. I use the GAIA 2 and the way they are built, it’s doubtful they would collapse at 5 extra pounds. I would go for it and not look back. The results are amazing.   If you are truly worried, call the company. 

My understanding is that all Isoacoustics products work most effectively when the weight they're carrying is right in the middle of their stated operational range.  These ranges overlap, so for optimum performance you probably need to step up to 1.

See the reviews of people who have gone from Gaia to Townshend. You can use Pods if you want to save some money but if you use Podiums the improvement will be a lot more. Yes they are expensive but compare the results. Everyone going from Gaia to Podiums saying it is well worth the extra. My 150lb Moabs are on Podiums. Not just improved. Transformed.

The OP was enquiring about Isoacoustics GAIA...and Not about a totally different manufacturers product that you seem intent of promoting !

Without knowing too much about the gaias, it seems like they work like a shock absorber or even springs on a car in terms of downward pressure the weight places on them. So, imagine you have a small set of springs and put a medium to large dump truck on them. They may or may not hold up the truck, but it may not be a smooth ride along bumps or steering etc... 
That is how I view the gaias and their weight capacity. I got the #2 just to be safe, although I was tempted to get the lighter capacity ones. 
It's not about breaking or holding up the speakers, but the footers doing their job in a capable way, instead of being overwhelmed by the weight.

From their website:

The GAIA model should be selected based on the weight that they are supporting. The weight limits we set are based on the performance curve. The GAIA perform well up to the specified weight limits, but once you are within 10% of the weight limit, we recommend using the next size up for best results. We do not recommend exceeding the weight limits of the GAIA’s or GAIA-TITAN’s.

5-10 lbs won’t make much difference whatsoever, they are conservative for optimum efficiency ,they will be fine.

I can’t speak for the Gaias use for speakers, but with the Oreas and my integrated and SACD player, going up to about 90% of the weight limit didn’t sound as good as going up to the next size and utilizing about 40-60% of the weight limit. The difference was noticeable.

I would assume that both Isoacoustic products are designed with similar values to be used.

All the best,

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.
