No Problem!...Didn't the PS-8a's have 8inch woofers? I cant remember...If so, I hope OCS also has the Eminense woofers in that size as well...What kind (disk or cone) and size of Passive Radiators do your ESS's have and what concerns have you come across with them? Hey, just for kicks, check this site out...just scroll down until you come across the PS-8a'S...Good luck on reading any of it though...p.s. Are ESS's being manufactured in Germany or something??
