ETI8X115B | PA System w/ (8) 15" Loudspeakers, 8-Ch Power Amplifier, Mounting Adapter for Commercial Installation, Birch Plywood, Black

The Sound Town ETI8X115B PA speaker system includes: (8) CARME-115BG3 15" 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-115BG3 loudspeaker features a 15" woofer and 1.75" titanium compression driver, delivering 450W RMS / 900W program power at 8Ω. The 90° × 60° rotatable horn and integrated multipurpose mounting adapter allow flexible installation and placement, supporting both 35mm pole mounting and fixed installation use, with horizontal (CARME-115BUB-H) or vertical (CARME-115BUB-V) wall-mount brackets available, sold separately. 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. FEATURES ETI8X115B COMMERCIAL PA SPEAKER SET: Includes (8) CARME-115BG3 loudspeakers and (1) ETi-84 8-channel power amplifier, delivering a fully integrated system with independent channel volume control for consistent coverage in conference, commercial, and installation environments. CARME-115BG3 15" LOUDSPEAKER: Features a 15" woofer and 1.75" titanium compression driver, delivering 450W RMS / 900W program at 8Ω for full-range performance. Includes a 90° × 60° rotatable horn and an integrated multipurpose mounting adapter for 35mm pole or fixed installation use. Horizontal (CARME-115BUB-H) or vertical (CARME-115BUB-V) wall-mount brackets are available, sold separately. ETi-84 8-CHANNEL AMPLIFIER: 1.5U rack-mount Class-D 8-channel amplifier delivering 8 × 800W RMS at 4Ω / 8 × 400W RMS at 8Ω for high-efficiency amplification in professional systems.
