All-New Acoustic Designs

From cone to cabinet, the PRX912 has been built from the ground up to leverage the latest JBL acoustic innovations. A patented JBL 2408H-2 1.5” compression driver with poly-annular diaphragm and neodymium magnet provides clear, detailed high-frequency response even at maximum volume. High-quality NTC thermistors protect transducers by reducing power sent to transducers when approaching thermal limit. Innovative new horns with updated JBL Image Control Waveguides provide optimum beamwidth and directivity. A next-generation woofer with ferrite magnet delivers smooth, natural bass and mids.

Power That Performs for You

PRX900 systems effortlessly support large performance spaces
with high power and performance needs. Driven by a highly efficient 2,000W (peak) Class D power amp, PRX912 provides acoustic clarity and definition with minimal power compression, even at maximum
volume. A bridged woofer amp keeps current spikes out of the ground and lowers crosstalk harmonics to the compression driver, and a power factor correction (PFC) power supply stabilizes voltage load sent to the amplifier. High-quality, high-linearity inductors deliver high power efficiency and low total harmonic distortion, and low-noise, low-distortion input gain staging optimizes range
and headroom for a diverse gain requirements. A high-quality DAC and ADC provide near-lossless audio conversion. And with a full-
bandwidth CMRR (Common Mode Rejection Ratio) greater than
55 dB and THD (total harmonic distortion) rating of <32 dB, system
noise is virtually nonexistent.
