jriggy, I am not sure so you should check with someone who knows but I think your cup may be half empty. The range for the GAIA IIs might be considered from 70-120 with the GAIA III being for 70 and under. But of course that puts 70 pound speakers at the upper limit of the GAIAIII. So I am just repeating what I was told. I did not question it further. You do bring up an interesting point. I don't think you should consider the range to be from zero to the max rated.
But I think the point is GAIAs still work within their range. Is it surprising that they would work differently with different weight? I think that would be expected.
Thanks for straightening out my thoughts on the math... yes, IF true, shooting for middle of 70 to 120 for a set of GAIA II’s makes sense. I’m at 102lb with my speakers, so that’s pretty close to center range.
I did contact ISOacoustics and got a responce within a few hours or so. The responder said “No I would not
say that is true that the units work best in the middle of their weight range.”
But I lean towards what you were told by the distributor...with their construction (rubber compound like the other ISO offerings?), it is not surprising that a set of GAIAs might
work differently with diferent weights.
I am going to wait and see if there is a coupon code or sale for Cruchfield coming up this weekend and order sets for my Daedalus Argos.
