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 environ-
ments,  the LSR6325P is ideal for stereo and surround sound recording, post production, and broadcast sys-
tems 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 verti-

cally, 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 ap-

plications and environments

Balanced XLR and unbalanced RCA inputs

 – Allows connection of professional and consumer audio equip-

ment 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.
