New England Audio Resource's NEAR-50M is a cyborg: metal innards in a wooden body. It represents NEAR's top statement in the firm's Metal Diaphragm Technology speaker line, which features the "NEAR-Perfect" driver cone. Metalin this case an anodized aluminum alloyis much more rigid than paper or plastic. Hence, a driver with a metal cone acts more nearly as a true piston. When it comes to loudspeaker cones, breaking up is not hard to do. When that happens, the cone flexes in a complex pattern, generating harmonic distortion. A typical plastic or paper 8" woofer may experience its first breakup mode at a frequency as low as 500Hz. The NEAR 8" metal-cone woofer's first breakup mode is said to be well above 2kHz, and their 4" metal-cone midrange does much better than that.
