JBL LSR Design for Sonic Accuracy
While most manufacturers take only a single on-axis measurement of the speaker's performance, this doesn't tell how it will sound in a room. JBL's LSR design criteria requires seventy-two measurements yielding more than 1,200 times more data, enabling JBL to engineer a speaker system that sounds right and is accurate in any room. A trademark of LSR Design is the custom waveguide that delivers superior imaging and smoother frequency response to your listening position.
High Output
Each model in the LSR2300 line produces exceptional sound pressure level (SPL) through JBL-engineered high-sensitivity transducers, high-output amplifiers and careful attention paid to the thermal properties of the system. Since heat is the enemy of output, JBL developed a low frequency port that doubles as a means of cooling of the amplifier output devices. Before becoming a production-ready design, every LSR2300 model survives the JBL Power Test in which the speaker must play at full rated output for 100 hours continuously, without failure.
Exceptional Bass Response
Today's music styles, film production and the demand for high-quality audio for HDTV require a monitor system capable of extended low frequency performance. To address this, JBL engineered new long-excursion transducers with high-flux motors. A custom tuned port works in concert with the transducers to produce deep and accurate Low Frequency Response, previously unavailable at this price point.
- High Frequency Transducer Tweeter Reproduces high frequency signals
- EOS Elliptical Oblate Spheroidal Wave Guide with Elliptical Tweeter Aperture Ensures the combination of direct and reflected sound arriving at the mix position is neutral and accurate. The Elliptical Aperture opening in the wave guide around the tweeter optimizes high frequency performance above 10 kHz.
- Low Frequency Transducer Woofer Reproduces low frequency content of the input signal
- Power Indicator Illuminates when power is connected and the Power Switch is set to ON.
- Low Frequency Port Works in conjunction with the low frequency transducer to provide accurate low frequency performance and air flow to cool the internal electronics.
- Input Panel Includes input connectors, power connector and user controls.
- Isolation Pad The speaker is equipped with a foam pad on the bottom surface to provide acoustic isolation from the supporting surface and increase stability when the speaker is placed on a speaker stand or console top.
- XLR Input Connect professional equipment using and XLR connector
- 1/4" Input - Connect equipment using a 1/4" balanced or unbalanced connector
- RCA Input Connect consumer equipment using an RCA input.
- Volume Control Use this control to Set the maximum listening level
- High Frequency Trim Allows boost or cut of High Frequency output by +/- 2.5dB
- Low Frequency Trim Allows a 2 dB boost of low frequency output by or 3 dB attenuation of low frequency output.
- Power Connector
- Fuse Holder Includes a user replaceable fuse and a spare fuse.
.
- Voltage Selector sets the operating voltage for compatibility with the voltage supply in the country of use
- Power Switch Activates power for the system.
- Low Frequency Transducer Woofer Reproduces low frequency signals
- Protective Grille Protects the woofer when the subwoofer is placed in a location where the woofer could be damaged by feet, or objects.
- Power Indicator Illuminates when power is connected and the Power Switch is set to ON.
- Feet Elevates the Subwoofer to prevent acoustic coupling with the floor and prevent scratching of the enclosure.
- Low Frequency Port / Low Frequency Port Works in conjunction with the low frequency transducer to
provide accurate low frequency performance and air flow to cool the internal electronics
- Input Panel - Includes input connectors, power connector and user controls.
- XLR Left and Right Inputs
- Left and Right Inputs
- RCA Left and Right Inputs
- XLR Left and Right Outputs
- Crossover Frequency Selector Allows selection of the crossover frequency: 80Hz, 120Hz or using the External setting enables use of an outboard bass management crossover.
- Polarity Switch Enables optional 180 degree reversal of the subwoofer output to optimize the blend of the subwoofer with the main speakers.
- Volume Control Controls the subwoofer level to balance the subwoofer with the system.
- Power Connector
