Cardeas revisited – Audio Physic's Cardeas III gains additional internal ceramic foam struts, then puts a 39mm floating tweeter, spiderless 150mm midrange with grid-lined sub chamber and two spiderless 180mm double-surround mid-bass couplers on the front which hand over to horizontally opposed 10" long-throw aluminium woofers on the lower cheeks. This 6-driver 4-way promises 25Hz-40kHz bandwidth and 89dB sensitivity and weighs in at a solid 72.5kg per side.
