SLS Loudspeakers introduced the new LS6593 and LS6593A line array speakers at AES 2005. The LS6593S/LS6593A concept is based on a woofer line array mounted on a front panel with a coaxially positioned ribbon tweeter array.
The woofer array comprises 6×5.25-inch drivers, while the tweeter array comprises 9×3-inch proprietary ribbon planar drivers driven from a passive crossover point of 2,000 Hz. The system delivers a frequency response of 80 to 20k Hz with an SPL of 94 dB referenced at 1W/1m and a calculated response of 118dB continuous and 124dB peak. The system handles up to 600W of amplifier power; 70V/60W versions are also available.
The low-frequency polycomposite cone woofers are mounted on a cast-aluminum chassis with the entire enclosure made of extruded aluminum weighing 30 pounds. The system is 32.2×7.5×8.3 (HxWxD).
