Post Subject: ConesPosted by KeaAudio on: 7/5/2010

HI Cat,

I would be able to send you a couple of cones to try. I understand that you can't pay much, but I am not giving them away either. So we can talk about cost via email. I am not sure what you mean by sandwich cone. The Goerlich speakers are not really sandwich. They just have a thin covering on the top. I would not consider that sandwich, but maybe that is what you meant.
We do not produce any sandwich because it is not needed (it actually only produces problems). Our material forms an airtight surface naturally when manufacturing. Also I am not sure what you mean by suspension. The suspension is usually the spider (fabric). But maybe you mean the surround. We do not have or produce Mylar surrounds, only rubber, for a good reason! I cannot see a point of Mylar anyhow. But maybe I misunderstood. A driver resonance frequency of 50Hz is only achievable with a very soft suspension (including soft surround) (I assume that is what you mean by cone resonance, the cone resonance is actually at 3500Hz and is dampened.
The 6-7" you are talking about, is that cone radius or frame radius? (our largest frame radius is 6.5")
looking forward to hear from you.
kind regards
J.Lang
