INTRODUCTION
Congratulations on choosing JBL MR
Series Loudspeakers. Their highly
accurate, uncolored and balanced
sound character will greatly increase
your enjoyment of recorded music
and movies. JBL speakers are built
with careful attention to detail, using
only the highest quality materials.
They will provide many years of
excellent performance.
The MR Series is the result of com-
bining traditional JBL Signature
Sound performance values with ele-
gant contemporary appearance.
Maximum Radiating Surface Area:
MR Series transducers utilize new
transducer technology by extending
the surface area of the cone allow-
ing for a shorter excursion of the
driver without sacrificing critical air
movement.
Maximum Efficiency: Larger air
movement coupled with shorter coil
movement allows the MR transducers
to be very efficient. See specifications.
Maximum Transducer Control:
Reduces distortion by tightening
the control of driver excursion and
increasing driver linearity.
Smooth, Accurate, Extended
Response: The MR series trans-
ducers, computer-optimized dividing
networks, and bass reflex cabinets
combine to give clear, crisp, accu-
rate, JBL Signature Sound.
PLACEMENT
Bookshelf Models: For the best
stereo reproduction, the two loud-
speaker systems should be an equal
distance from your listening position
and separated so that the angle
between them, at the listening posi-
tion, is between 40 and 60 degrees
(see Fig. 1). For example, if your lis-
tening position is 8 to 12 feet (2.5m
to 4m) from each speaker, the two
systems should be about 8 feet
(2.5m) apart. Placing the loudspeak-
ers in corners or against a wall will
result in the strongest (not necessa-
rily the most accurate) bass. Except
for the M5, all MR Series speakers
have their ports in the front so you
can place the rear of the speaker up
against a wall. In the case of the M5,
do not place the speaker closer than
3 inches (75mm) to the wall behind it
if possible.
For the best stereo imaging, we rec-
ommend that the systems be placed
so that the high frequency transduc-
ers are positioned approximately at
ear level of a seated listener. Every
room is different and there are differ-
ent tastes, so don’t hesitate to experi-
ment on your own.
Tower Models: The Tower models
cabinet height and driver placement
allow for speaker placement directly
on the floor. For the best stereo
reproduction, the two loudspeaker
systems should be an equal distance
from your listening position and sepa-
rated so that the angle between
40°-60°
