Description: Three-way vented-box loudspeaker. Drive-units: 1" (25mm) metal-dome tweeter, 6" (160mm) woven-Kevlar FST midrange cone, two 10" (250mm) paper-Kevlar cone woofers. Crossover frequencies: 350Hz, 4kHz. Frequency response: 25Hz-50kHz, -6dB; 32Hz-42kHz, -3dB; 37Hz-23kHz, ±2dB on reference axis. Dispersion: within 2dB of on-axis response over 60 degrees horizontal or 10 degrees vertical. Sensitivity: 91dB SPL (2.83V/m). Harmonic distortion (second and third harmonics, 90dB/m): <1.0%, 45Hz-20kHz; <0.5%, 50Hz-20kHz. Impedance: 8 ohms nominal, 3 ohms minimum. Recommended amplification: 50-1000W into 8 ohms on unclipped program. Maximum recommended cable impedance: 0.1 ohm.
Dimensions: 46.7" (1197mm) H by 17.5" (450mm) W by 25.2" (645mm) D. Net weight: 275 lbs (125kg) each.
