It is almost ten years since I last heard a pair of DCM loudspeakers, the Time Windows made famous by writer Peter Aczel in the first incarnation of his magazine The Audio Critic. The "Time" nomenclature traditionally used by DCM in their models refers to the fact that for any hi-fi component, its performance in the frequency domain is related to, and implicit in, that in the time domain, the two being connected by the mathematics of the Fourier Transform. To put it in simplistic language, a speaker's impulse response can be translated directly into its frequency response: all the information needed to show how its response varies with frequency is contained in the shape of the impulse it produces.

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'."

Long-lived loudspeaker models are rare. So it's surprising that the two-way, stand-mounted Model 5, the smallest speaker made by Massachusetts-based Aerial Acoustics, was revised just once between 2015 and April 1997, when Robert Harley favorably reviewed it and it cost $1800/pair. The revised 5B was equally favorably reviewed by John Marks in July 2009. This kept the original's 1" titanium-dome tweeter and sealed-box woofer loading but replaced the 7" polypropylene-cone woofer with a 7.1" laminated-fiber–cone woofer. Despite more than a decade's worth of inflation, the price rose only slightly, to $2400/pair.

There is a tendency in magazine publishing to concentrate on the present. Writers generally downplay what happened in the irretrievable past as being of lesser importance compared with the new and exciting, their enthusiasm pretty much tied to the ever-in-motion time-line. I instituted Stereophile's annual "Products of the Year" feature, therefore, to give recognition to those components that had proved capable of giving pleasure beyond the formal review period. To confound confusion, there are just five individual categories: "Loudspeakers" (including subwoofers); "Amplification Components" (preamplifiers, power amplifiers, etc.); "Digital Sources" (CD players, transports, D/A processors); "Analog Sources" (phono cartridges, turntables, tonearms, FM tuners, etc.); and "Accessories" (everything else).
