Anthony Gallo Reference 5LS Line Source Speaker
It's just a prototype for now, but Anthony Gallo Acoustics (AGA) demoed - for the first time ever - its all-new Reference 5LS line source loudspeaker in the Venetian Hotel at CES. Scheduled to be released to the public in the third quarter of 2007, the towering speaker stands 78" tall, boasts an incredible 12 custom aluminum 4" woofers and features seven of AGA's proprietary CDT II tweeters. According to Gallo, these tweeter "possess power-handling, offaxis response and efficiency that approach the textbook definition of ideal." In addition, the Reference 5LS has eight 4" carbon fiber midrange drivers, each housed it its own 5" spherical enclosure.
The Reference 5LS is designed as the "big brother" of their flagship Reference 3.1. While it's not completely omnidirectional, Gallo states that it is the closest any line source has ever come to being omni-directional.
Many line sources horizontally offset their various drivers, but AGA alternates tweeter cylinders with mid-range spheres - one atop the other - in perfect vertical alignment. Because of this, they claim that the phase and dispersion problems caused by driver offset are entirely eliminated.
Capable of being driven by a single, capable 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 crossoverless design and high efficiency of both the CDT II 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.
At 7" wide by 11" deep, the Reference 5LS sports quite a slender profile. The twelve 4" woofers fire out the back and equal the cone surface of a 15" subwoofer. In addition, the Reference 5LS features AGA's patented S2 Technology, as well as their trademark spherical enclosure, which is designed to eliminate any external diffraction.
