Kea Audio,

Regarding the driver. When I meant hard suspension I meant low excursion. Acoustic pressure equals displacement by volume and displacement equals surface by excursion. In horn we add the horn EQ, so for a given frequency we might have lower excursion, still managing to hit targeting frequency. Sure, with limited cone size we will be obliged to soften suspension but we in horn situation will be doing to lesser degree then it would be in case if it was a direct radiator. So, I would probably need to talk about the concept of “minimum stiffness”. Compression chamber sure will stiffening suspension and driver resonance up but still I would like to find somehow a way to cone to be hard-suspended, still having small size and low resonance. I know that I am taking about impossible things… but I am also talking about a driver that does not exist.

BTW, do you use any other surrounds in your cones besides rubber?  How about the leather-like materials or plastics?
