Applications:

e SRX812 is a passive portable PA speaker in the SRX800

series from JBL Professional. It has been designed to deliver

class leading performance in a variety of applications

including use as a main PA, a stage monitor, and rear and side

lls. When used in conjunction with the other SRX800 full

range systems and the SRX800 subs, SRX812 in an integral

part of a high performance, fully congurable 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, ecient, 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 Dierential Drive Technology for reduced weight

while maximizing power amp eciency. 3” voice coils and

dual ferrite drivers deliver exceptionally low distortion and

extended low frequency response.

e SRX812 is supported with tunings for Crown XTI 2

ampliers, Crown Itech HD ampliers, and dbx DriveRack

360 signal processors, all of which can be controlled as part

of a comprehensive system with Harman Audio Architect.

With best in class 18mm wooden enclosures , 14 gauge steel

grilles, and JBL’s Patented DuraFlex nish, SRX800 speakers

are built to last and withstand a lifetime of hard tour use.
