Anthony Gallo Acoustics' new Reference 5LS is the culmination of everything Anthony Gallo has learned during a lifetime of speaker design. Long-awaited "Big Brother" to the acclaimed Reference 3.1, the Reference 5LS builds upon its smaller sibling's considerable strengths, achieving even greater performance in virtually every aspect of sound quality. Measuring a full 78" in height, this state-of-the-art line source spans the gamut of frequency- and dynamic-range, yet its slender 7-inch width and 11-inch depth enable it to excel in virtually any listening room and blend beautifully into most decorating schemes.
The cornerstone of the Ref 5LS' performance is Anthony Gallo Acoustics' patented CDT(TM) tweeter, whose power-handling, off-axis response and efficiency approach the textbook definition of ideal. Midrange drivers employ Spherical Enclosure Technology, which virtually eliminates enclosure resonance and diffraction while enabling broad dispersion. The 5LS is also the world's first speaker to use multiple CDT tweeters: to form the line array, Anthony Gallo Acoustics deploys seven CDTs and eight 4-inch carbon fiber midrange drivers, each housed it its own 5-inch spherical enclosure. Although most line sources must horizontally offset their various drivers, Anthony Gallo alternates Tweeter cylinders with Midrange spheres, one atop the other, in perfect vertical alignment. As a result, the phase and dispersion problems caused by driver offset are entirely eliminated. Twelve aluminum, rear-firing 4-inch subwoofer drivers equal the surface area of a 15-inch driver, but reproduce bass with a speed and transparency that no large driver can approach. The tubular stainless steel bass enclosure is stuffed with Anthony Gallo Acoustics' S2 acoustic fill (also patented), which further enhances the quality and quantity of low frequency output.
Capable of being driven by a single amplifier, the 5LS offers the options of bi- or tri-wiring, as well as bi- or tri-amping. Although capable of handling massive power, the crossover less design and high efficiency of both the CDT tweeters and carbon-fiber midrange drivers are perfect matches for low-powered, high performance amplifiers. The first-order low-pass filter used for the bass drivers (The ONLY crossover employed in the 5LS!) can be bypassed, enabling the LF enclosure to be driven from the LFE output of a processor, or from a separate amplifier. The (optional) Reference SA amplifier, which features volume, phase and crossover adjustments, is ideal for this application, as the speaker can be placed for optimal imaging and soundstaging performance and then fine-tuned for bass using the SA's control facilities.
