ETI8XU108B | PA System with Eight 8" Wall-Mount Speakers and 8-Channel Power Amplifier for Commercial Installations, Birch Plywood, Black

The Sound Town ETI8XU108B PA speaker system includes: (8) CARME-U108BG3 8" 2-Way Loudspeakers (1) ETi-84 8-Channel Power Amplifier *Speaker wire not included. See FAQ for details. Designed for distributed audio applications, it provides independent per-channel volume control for consistent coverage and clear sound reproduction across commercial installation environments. Each CARME-U108BG3 loudspeaker features an 8" woofer and 1.4" titanium compression driver, delivering 175W RMS / 350W program power at 8Ω for balanced full-range output. A 90° × 60° rotatable horn allows flexible coverage control, while the included U-bracket supports secure wall-mounted installation. The durable 5/8" plywood enclosure with a heavy-duty metal grille ensures reliable performance in both fixed installations and mobile setups. The MODE Audio ETi-84 is a 1.5U rack-mount 8-channel Class-D amplifier delivering 8 × 800W RMS at 4Ω / 8 × 400W RMS at 8Ω. It provides stable multi-channel power distribution, with 8 balanced XLR inputs and terminal block outputs for straightforward integration. A heavy-duty metal chassis combined with Power Factor Correction (PFC) ensures efficient operation, reduced heat, and dependable long-term performance. Compared to 70V/100V systems, this low-impedance set provides direct amplifier-to-speaker drive without line transformers, delivering improved clarity, strong dynamics, and accurate transient response, making it well-suited for installations requiring clear, consistent sound.
