and M2 Master Reference Monitors and sporting a sleek, modern design, JBL 308P MkII delivers outstanding
performance and an enjoyable mix experience at an accessible price.
YOUR MIX IS ONLY AS GOOD AS YOUR MONITORS
JBL 308P MkII has been equipped with acclaimed 3
Series transducers that now perform even better. Hear
deep, accurate and tightly controlled bass, thanks to a
long-throw 8" woofer and the patented JBL Slip Stream™
low-frequency port. Enjoy soaring, immaculately detailed
highs, via its woven-composite 1" Neodymium tweeter.
JBL engineers took things to the next level with faster
HF transient response through fine-tuned ferrofluid
damping, and greater low-frequency linearity and reduced
harmonic distortion courtesy of an enhanced woofer
design. The result is a studio monitor you can trust—with
unmatched performance, stunning imaging and neutral
frequency response that’s unbeatable in its class.
TAILORED SOUND TO FIT YOUR STUDIO
The dimensions and acoustics of a room can have a
major effect on sonic accuracy, and that’s why JBL 308P
MkII lets you adjust the response to fit your studio. The
new Boundary EQ attenuates the low-end boost that can
occur when you place monitors directly on the desktop
or near walls. The 3-position HF Trim switch allows you
to adjust the high-frequency response of the 308P MkII
to tailor it to room acoustics or personal tastes.
PATENTED IMAGE CONTROL WAVEGUIDE
Reveal impressive detail, ambience and depth in your
mixes with JBL 3 Series’ groundbreaking Image Control
Waveguide. Originally developed for JBL’s flagship
M2 Master Reference Monitor, this patented innovation
ensures an acoustically seamless transition between the
low- and high-frequency transducers and provides an
immersive soundstage, with precise imaging. Offering a
wide sweet spot and neutral frequency response, JBL 308P
MkII delivers a crystal clear representation of your mix,
revealing subtle details, even when listening off-axis.
BIG SOUND OUT OF THE BOX
JBL 308P MkII is ready for the most demanding production
styles right out of the box. With 112 watts of total power, the
dual, integrated Class-D power amplifiers, custom designed
by JBL for each transducer, give you generous dynamic range
for any project. From music production and podcasting to
cinematic sound design or daily vlogging, enjoy the output and
power you need to hear exceptional detail at any volume—
even at peak SPL. Simply plug in, power on, and start creating.
