Introduction

Congratulations on your purchase of the LSR6325P Bi-Amplifi ed Studio Monitor, the newest member of the

LSR6300 Series product line. The LSR6325P system incorporates patented JBL transducer and system
technologies designed to provide ultra-accurate response and exceptional SPL capability in a very compact
form-factor. THX® pm3™ approved for use in the most demanding production applications and environ­ments, the LSR6325P is ideal for stereo and surround sound recording, post production, and broadcast sys­tems where space is limited but accuracy and high-output are a requirement. Because production rooms are
acoustically less-than-perfect, JBL Professional has incorporated technologies in the LSR6325P to overcome
problems in the room. The result: clear accurate sound at the listening position in any room.

LSR6325P Features

5.25” Woofer with JBL Symmetrical Field Geometry (SFG) ® technology – Excursion is maximized by
using a massive 1.5” drive coil, while maintaining excellent distortion characteristics. The heavy magnetic
structure keeps power compression to a minimum reducing spectral shift as power levels increase. The
result is exceptional low frequency output and accurate spectral response at all listening levels.

1” Titanium Composite High Frequency Transducer – Using patented technology, the high frequency
device incorporates titanium and composite materials to improve transient response and reduce distortion.
By reducing distortion in the lower operating range, where the ear is most sensitive, ear fatigue is radically
reduced.

Elliptical Oblate Spheroidal (EOS) Waveguide – Designed for a targeted listening window of +/- 15º verti­cally, the EOS provides a frequency response through the entire window of 1.5 dB from on-axis response.

Di-cast aluminum enclosure – The rigid aluminum enclosure provides a high-inertial ground for optimum
transducer performance and low resonance.

Linear Dynamics Aperture – Contoured ports virtually eliminate high-end turbulence found in traditional
port designs. This provides more accurate low frequency performance at higher output levels.

THX® pm3™ approved – The LSR6325P is THX approved for use in the most demanding production ap­plications and environments

Balanced XLR and unbalanced RCA inputs – Allows connection of professional and consumer audio equip­ment and computer recording workstations.

High Frequency Adjustment with three settings – allows you to tailor high frequency response to taste,
environmental conditions and program requirements.

80 Hz High Pass Filter – allows use with sub woofers without bass management.

Front-panel volume control – provides conveniently located volume adjustment in computer recording and

table-top production applications.

LSR6325P Features to Tackle the Problems in the Room

LSR – Linear Spatial Reference Te chnology
JBL Developed Linear Spatial Reference Te chnology to optimize mid and high frequency accuracy at the
listening position where relected sound comes into play. Meeting frequency response criteria for seventy-two
off-axis measurements, the LSR6325P ensures that not just the direct sound,
reaches you at the listening position is also smooth and accurate.

Boundary Compensation - A Boundary Compensation switch restores accurate bass response when the
loudspeaker is wall mounted, positioned close to walls, corners, placed on work surfaces or console meter
bridge.

Magnetic Shielding – The LSR6325P is magnetically shielded to allow use in close proximity to CRT video
and computer displays.

Mounting Options – The LSR6325P enclosure includes mounting points to provide flexibility and allow you to
optimize placement, particularly in small environments. Mounting points are compatible with industry-stan­dard mounting hardware.

Optional LSR6312SP Subwoofer with Room Mode Correction - The use of an optional LSR6312SP
powered subwoofer in your LSR6325P system adds the powerful bene t of Room Mode Correction. The RMC
circuit in the LSR6312SP and the included RMC Calibration Kit allow you to identify and compensate for
troublesome low frequency standing waves. The result is clear extended bass response at the mix position in
any size room.

Unpacking – Caution: The high-frequency transducer is unprotected and can be damaged if touched while
unpacking the speaker. An easy way to safely unpack your monitors is to open the top of the box, keep the

ller piece on and roll the box upside down. The box can then be slipped off. This also works in reverse for

repacking the system.

Placement – Speaker Placement
Listening Distance: In a stereo close-field application the speaker is typically placed 1 to 1.5 meters (3-5 feet)
from the listening position. In mid- eld or surround sound applications, 2-3 meters is typical. The field in a
stereo listening application is optimized by arranging the speakers to form an equilateral triangle where the
distance between the two speakers equals the distance of each speaker to the listening position. Vertical vs.
Horizontal Placement: The LSR6325P system is designed for vertical orientation which provides broad lateral
dispersion and controlled vertical dispersion to optimize the size of the listening window and minimize reflec­tions off the work surface and the ceiling. Horizontal placement will limit the size of the listening window and

increase reflections which can result in cancella

Angling towards the listening position: The LSR6325P should be angled so the center of the high frequency
transducer points directly at the listener’s ears.
