The LSR4300 Series Studio Monitors are designed for critical stereo and multi-channel audio production applications that require exceptional spectral accuracy and high SPL capability. Acknowledging that much of today's production is carried out in acoustically untreated rooms, the LSR4300 Series is the first professional monitor to combine JBL's Linear Spatial Reference technology and automated RMCTM Room Mode Correction, an onboard system that automatically compensates for low frequency anomalies measured at the mix position. The LSR4300 enhances computer-based production by incorporating system-wide volume control, input source selection, individual speaker solo and user EQ. Harman HiQnetTM Network protocol enables centralized system-wide control from any speaker, wireless remote control and computer using LSR4300 Control Center Software.
438H Low Frequency Transducer
The 6 in. woofer utilizes a powerful, shielded neodymium magnet of light weight which can be used in close proximity to CRT-type monitors with no interference. The transducer utilizes a copper-clad polepiece that improves high frequency output by reducing voice coil inductance. A copper ribbon voice coil ensures high sensitivity, and a flux shorting ring stabilizes the magnetic field in the gap, reducing distortion. Heat sinking has been placed close to the magnetic gap in order to draw out heat as efficiently as possible. The cone is polymer coated for uniformity of response over the woofer's passband.
