JBL LSR-4328P - Two-Way 8" Bi-Amplified Studio Monitor (Single)
Key Features
  • Bi-Amplified Power System
  • 8" Woofer with 150W of Output
  • 1" High-Frequency Driver with 70W Output
  • RMC System For Tuning Speakers to Room
The single LSR-4328P - Two-Way 8" Bi-Amplified Studio Monitor from JBL has a bi-amplified power system that provides its 8-inch woofer with 150 watts of output and its 1" high-frequency driver with 70 watts of output. The monitor features JBL's automated RMC (Room Mode Correction) system, which, when used in conjunction with the included calibration microphone, can compensate for the low-frequency resonances in your room with the built-in digital EQ. This provides a more accurate playback of your tracks by having your monitors tuned uniquely to your workspace.

JBL 4328P Overview

The single LSR-4328P - Two-Way 8" Bi-Amplified Studio Monitor from JBL has a bi-amplified power system that provides its 8-inch woofer with 150 watts of output and its 1" high-frequency driver with 70 watts of output. The monitor features JBL's automated RMC (Room Mode Correction) system, which, when used in conjunction with the included calibration microphone, can compensate for the low-frequency resonances in your room with the built-in digital EQ. This provides a more accurate playback of your tracks by having your monitors tuned uniquely to your workspace.

Utilizing the Harman HiQnet network protocol, you can control a multi-speaker system of LSR-4328Ps from any of the speaker's front panels, the included wireless remote control, or a computer via the monitor's USB port and the included Control Center Software. Multiple speakers can be networked via their RJ45 ports and CAT5 cable.

The LSR-4328P provides a variety of digital and analog input options. On the analog end, the monitor has a single XLR input and a 1/4" TRS jack with selectable 4 or -10dBV sensitivity. Its built-in A/D convertor allows it to accept digital AES/EBU XLR input as well as S/PDIF.

438H Low-Frequency Transducer
The 8" 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 is designed to improve 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
431G High-Frequency Transducer
The high-frequency transducer has a treated silk diaphragm that produces uniform sound. Its flat ribbon aluminum voice coil ensures low-moving mass and enables the transducer to achieve response out to 22 kHz. A lightweight neodymium magnet structure with integral heat sinking, along with Ferrofluid in the magnetic gap, enables the transducer to produce high-peak output levels with minimal power compression. The magnet structure is integrally shielded, enabling the system to be used in proximity to CRT-type monitors with no interference
Bi-amplified Power System
The LSR4328P incorporates two high-power amplifiers that provide 150 watts of power to the low-frequency transducer and 70 watts of power to the high-frequency transducer. A precision digital dividing network having high-order Linkwitz-Riley slope characteristics for smooth transition between transducers, results in imaging and lack of time smear
Advanced LSR Linear Spatial Reference Design provides neutral off-axis response for greater clarity at the mix position
Harman HiQnet Network Protocol enables system-wide control of level, EQ, input selection, solo and more
Wireless remote control and LSR4300 Control Center Software enable control from the listening position
Front-panel output meter with variable brightness displays signal level
Integrated mounting points allow wall mounting for greater placement options
Built-in handles facilitate optimum positioning
