The JBL 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 variety 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 72 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.
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 incorporates 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. The high frequency device is a 1" composite diaphragm integrated with an Elliptical Oblate Spheroidal (EOS) waveguide with 60 x 100 degree dispersion, which is critical to the smooth spatial response required in today's working environments.
The LSR6325P-1 combines two high-power amplifier sections with an active crossover system, 100 watts of low-frequency power and 50 watts to the high-frequency section provide maximum dynamic range. A bi-color LED indicates power and any onset of clipping in either amplifier section. Active crossover circuitry results in a 24 dB/Octave Linkwitz-Riley electroacoustic response between low and high frequency devices for smooth transition in both the frequency and time domains. This results in exceptional imaging, a lack of time smear and superior off-axis response linearity.
A variable level control and dual input sensitivities allow use with a broad range of professional and semi-professional equipment. Balanced and unbalanced signals can be accommodated with an XLR input. An unbalanced RCA input is also provided. The frequency response can be gently tailored to compensate for placement and room absorption characteristics. Users can select between two different high frequency response contours.
A low-frequency filter at 80 Hz can also be added for use with subwoofers that contain their own low pass filtering. A unique Boundary Compensation control adjusts the bass and mid-bass output for optimum performance when the system is positioned near a boundary, on the meter bridge of a console or work surface.
