ETI8X115B | PA System w/ (8) 15" Loudspeakers, 8-Ch Power Amplifier, M

DESCRIPTION

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.

FAQ

Q: What speaker wire should be used for this system?

A: Speaker wire is not included. To ensure optimal performance and minimize signal loss, select the appropriate wire gauge based on the distance between your amplifier and speakers:

Distance	Wire Gauge
10–15 ft	18 AWG
15–25 ft	16 AWG
25–50 ft	14 AWG
50–100 ft	12 AWG
Over 100 ft	10 AWG

Using a thicker (lower gauge) wire for longer runs helps maintain signal strength and overall audio quality.
