part of a high performance, fully congurable loudspeaker
system.
e SRX812 features premium JBL Transducers. High
frequencies are handled by an annular polymer diaphragm
compression driver that features a best in class 3” voice
coil coupled to a 1.5” throat opening. Using a neodymium
magnet, the compression driver is lightweight, ecient, and
extremely powerful. is delivers very high power levels
with reduced distortion and increased phase coherence
resulting in smooth, crystal clear high frequencies. For Low
Frequencies, the SRX812 uses a 12-inch woofer with JBL’s
patented Dierential Drive Technolog y for reduced weight
while maximizing power amp eciency. 3” voice coils and
dual ferrite drivers deliver exceptionally low distortion and
extended low frequency response.
