RSL Speedscreen II loudspeaker
RSL is the house brand of a California chain of retail stores, Rogersound Labs, that is part-owned by the leader of the RSL loudspeaker-design team, one Howard Rodgers. (Rogersound Labs also owns the Upscale Audio high-end store in north Los Angeles.) The range offered by RSL is unbelievably wide, with models addressing just about every market niche and price category. The Speedscreen II, however, is Howard's attempt to produce a true high-end loudspeaker at an affordable price. To the casual observer, the Speedscreen ($898/pair) appears to be a planar design; however, its shallow, braced enclosure houses moving-coil drive-units, and is a result of Howard's attempts to minimize the effect of cabinet resonances. "I always thought deep, narrow enclosures sound 'boxy'," said Howard when he visited Santa Fe last September, "and the wide but shallow cabinet seemed to be the best way to get a large internal volume without 'boxiness'."
For anyone who wants to be up to date on all the audio products available in North America, Audio's Annual Equipment Directory is an indispensable source of information. (So is the publication you're reading now, of course.) The 1992 Directory (aka Audio's October issue) arrived when I was finishing up the review of the Acarian Alón IV (see
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.
