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

This innovative technology offers far greater efficiency in loudspeaker design, where a ring of extremely rigid carbon fiber is 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,” explains 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. A narrow surround 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 product lines.
