The JBL's 8128 is a cost-effective, 8-inch full-range loudspeaker for commercial purposes. This public address system has high-fidelity performance in a convenient package. High-sensitivity drivers in the system deliver maximum sound volumes with minimal amplifier power. The 8100 series adds elegance and performance to basic commercial sound systems or any application that does not require a back can for installation, thanks to its contemporary grill design, 70V/100V taps, and open-back design.
