THX pm3
The LSR6325P-1 Studio Monitor
provides ultra-accurate response and
exceptional SPL capability in a very
compact form factor. THX pm3
approved, the LSR6325P-1 is ideal for
stereo and surround recording, post
production and broadcast systems
where space is limited but accuracy
and high-output are required. The
LSR6325P-1 Studio Monitor combines
JBL's latest in transducer and system
technology and incorporates the LSR
Linear Spatial Reference design to
provide greater accuracy at the mix
position. The Linear Spatial Reference
(LSR) philosophy is based on a set of
design goals that optimize the overall
performance of the system in a vari-
ety of acoustic spaces. Instead of
focusing on a simple measurement
such as on-axis frequency response,
LSR design requires the system meet
frequency-response criteria for seven-
ty-two off-axis measurements.
Carefully-controlled dispersion,
achieved through transducer design,
crossover frequency selection and
engineering of the enclosure, ensures
not just the on-axis sound, but also
the reflected sound which reaches of
the mix position is neutral.
By incorporating LSR into the system design the LSR6325P-1 delivers greater
high and mid frequency accuracy to the mix position, in a broad range of
production environments.
Low Frequency Transducer
The 5.25" woofer is based on JBL's research and field proven experience
in low distortion, high excursion designs. The cone forms a rigid piston and
is supported by a butyl rubber compliance. The motor structure incorpo-
rates Symmetrical Field Geometry (SFG) with an integral shorting ring for
maximum linearity. The high excursion capability provides a substantial
increase in dynamic range over typical transducer design. A cast aluminum
basket provides advanced heat dissipation for low power compression. The
powerful structure is shielded for use in close proximity to CRT monitors.
High Frequency Transducer
The high frequency device is a 1" composite diaphragm integrated with
an Elliptical Oblate Spheroidal (EOS) Waveguide with 60 x 100 degree dis-
persion which is critical to the smooth spatial response required in today's
working environments.
