Superior Audio Reproduction

The LSR4328P incorporates JBL's Linear Spatial Reference Technology, this matches the exact geometry of the 4300's waveguide design with the transducers and crossover network, resulting in an optimised frequency response at the mix position. JBL's next generation RMC system - Room Mode Correction - integrates a powerful analyser into each speaker, this then automatically analyses and compensates for both low frequency standing waves and boundary conditions. Simply plug the LSR4300 calibration microphone into the speaker, push a button and let the innovative technology do the rest.

Powerful Network Functionallity

The LSR4328P features a powerful DSP platform that provides full system networking and communications. The LSR4300 Control Center software utilises the Harman HiQnet™ which allows centralised control of a multi-channel system via any speaker's front panel, wireless remote control or computer via a standard USB connection. Harman HiQnet™ also enables synchronised RMC calibration of all speakers when connected to the same network.

Flexible and Comprehensive Control

Each speaker's front panel, wireless remote control or Control Center Software offers complete control of System Level, Individual Speaker SOLO, Input Source Selection, high and low frequency EQ settings, and adjustment of all parameters. Now you can adjust every setting within your monitor setup from anywhere in your studio.

Solo or Surround Use

The LSR4328P are suitable for a wide range of applications, from simple stereo mixing in a home studio to complex surround production in a professional studio. The system can be configured with up to eight main speakers, in any combination of 6'' LSR4326P and 8'' LSR4328P models. Additionally, the system is automatically aligned so that the sound arriving at the mix position from all speakers is synchronised to guarantee a precise image regardless of each speaker's actual placement.
