Data Sheets
JBL 708P is the self-powered reference monitor for critical music recording, lm post and broadcast production
applications. The 708P leverages new patent-pending driver technologies and JBL’s renowned Image Control
Waveguide to deliver extraordinary output, stunning detail, an expansive sound stage, and greater accuracy
in a broad range of rooms. 708P delivers several times the output of other comparably-sized studio monitors,
providing signicantly greater dynamic range and greater working distances.

8” Bi-Amplified Master Reference Monitor
NEXT-GENERATION DRIVER TECHNOLOGY
JBL 708P leverages JBL patents and next-gen driver
technologies to provide unparalleled output with greater
dynamic range and extended frequency response in
demanding production applications. The JBL 2409H high-
frequency compression driver incorporates an innovative low-
mass annular diaphragm to deliver smooth response beyond
36 kHz, with extraordinary output and very low distortion.
The 728G low-frequency transducer leverages JBL patented
Differential Drive technology to reduce power compression for
greater sustained output and extended, linear low-frequency
performance below 35 kHz. These proprietary drivers allow the
708P to deliver two to three times the output of conventional
studio monitors.
PATENT-PENDING IMAGE CONTROL WAVEGUIDE
First introduced in the JBL M2 Master Reference Monitor,
the JBL Image Control Waveguide ensures accuracy
and neutrality while providing a wide sweet spot with
increased sonic detail. By enabling an acoustically
seamless transition between the woofer and high-frequency
transducer, the waveguide provides a detailed sound
stage and accurate imaging across the entire frequency
spectrum. Smooth, neutral on- and off-axis frequency
response allows the JBL 708P to deliver neutral response
across a wide listening area in a broad range of rooms.
INTEGRATED DUAL AMPLIFICATION SYSTEM
JBL 708P features a built-in dual amplification system
that’s optimized for its high-output drivers. A 120W amp
powers the 2409H high-frequency transducer, while
a 250W amp is dedicated to the 728G low-frequency
transducer. This combination delivers unparalleled output
and detail at greater listening distances, making the 708P
ideal for post production or mastering environments.
COMPREHENSIVE DSP-BASED EQ
Although the 708P design yields exceptional neutrality
in any room, the monitor also features on board room
equalization, so you can compensate for the adverse effects
of room acoustics and enjoy the most accurate sound
reproduction in any listening environment. In addition to
twelve bands of Room EQ, eight bands of User EQ allow
customized response curves such as the X-Curve, and
compensation for “screen-loss” when placed behind a
perforated cinema screen. User-enabled digital delay
allows virtual alignment of speakers relative to the listening
position, while additional AV Synchronization delay is
available to compensate for latency in video displays.
