US company Community Professional Loudspeakers has been granted a patent by the United States Patent and Trademark Office (USPTO) for its work on Carbon Ring Cone Technology.

Greater efficiency that alternative loudspeaker designs is achieved with a ring of extremely rigid carbon fibre placed around the outer edge of a specially designed cone, resulting in a structure that is both lighter and stiffer than a conventional cone. ‘An ideal loudspeaker cone would be infinitely rigid and have no mass,’ says Community Founder and President, Bruce Howze. ‘Carbon ring cones are a realistic step toward this ideal.’

The increased edge strength also enables the use of a deeply pleated narrow surround, which permits a larger cone diameter, providing greater piston area in a given frame size. ‘In short, a carbon ring cone is lighter, larger, and stronger,’ says Howze. ‘A speaker employing a carbon ring cone will have higher sensitivity, higher mechanical power capacity and reduced cone break-up.’

Community's newly patented Carbon Ring Cone Technology is employed in its Veris, S-Series and R.25 lines.
