      OVERVIEW

      Automatically analyzes and corrects the sound for accurate mixing.

      The JBL LSR4326P Studio Monitors are designed for critical stereo and multichannel audio production applications that require exceptional spectral accuracy and high SPL capability. Exclusive technology from JBL automatically analyzes and corrects the response of each speaker in the room for absolute accuracy in mixing.

      Acknowledging that much of today's production is carried out in acoustically untreated rooms, the LSR4300 Series are the first professional monitor speakers 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.

      Network and Digital Features

      The JBL LSR4300 series speakers enhance computer-based audio production by incorporating systemwide volume control, input source selection, individual speaker solo and user EQ. They use the Harman HiQnetTM network protocol that allows centralized control of a multichannel system from any speaker's front panel, wireless remote control, or computer via a standard USB connection and LSR4300 Control Center Software. The network is configured using supplied CAT5 cable and by setting a DIP switch on each speaker. Harman HiQnet also enables synchronized RMC calibration of all speakers on the network.

      438H Low Frequency Transducer

      The 6.25" woofer in these JBL speakers uses a powerful, shielded neodymium magnet which can be used in close proximity to CRT-type monitors with no interference. The transducer uses 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.

      431G High Frequency Transducer

      The JBL studio monitor's high frequency transducer has a treated silk diaphragm that produces uniform and smooth sound. Its flat ribbon aluminum voice coil ensures low-moving mass and enables the transducer to achieve response out to 22kHz. A lightweight neodymium magnet structure with integral heat sinking, along with ferrofluid in the magnetic gap, enable 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 JBL LSR4326P monitors incorporate 2 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 exceptional imaging and lack of time smear. The circuitry also yields a tonal-artifact-free noise floor.

      Get Your Money's Worth

      By GHP

      Comments about JBL LSR4326P STU REF MON:

      These really reveal every nuance. They have RMC (room mode correction) built in, and it is very understated. The reference mic calibration allows for mixes to be accurate within 0.25db with these monitors, and with 4312 sub you can solo these and use the crossover to mimic much smaller monitors! Also the 4312 sub it is accurate within 0.5db from the crossover down - and believe it or not, once you?ve used these, you can tell!There is no longer a need for foaming up your studio walls or insulating everything to get a good mix or master. Of course doing those things in addition to RMC will definitely help, but they are only complimentary. The RMC on these ?flattens? your room sound by addressing phasing issues with regard to the time it takes for a certain frequency to leave the monitor & get to your head, as well as amplification needed to compensate for nearby boundaries! The silk dome tweeters are so pleasing to the ear that you can listen to these all day with no fatigue and the stereo field is out of this world.You?ve gotta love these things. They are so perfect. My personal favorite is the option of 24bit S/PDIF input on these with RMC (room mode correction). The digital input allows for uncolored monitoring of your mix, no humming from analog cables, etc. If I turn them up to their max when nothing is playing thru them, I can?t hear the amplification unless I literally put my ear to the wave guide! The are outstanding! I use these for my regular computer monitors too! I have a MAC PRO which has S/PDIF output. I got a TOSLINK to COXIAL adapter for them, and if I?m listening to something online, it can actually sound good (LOL) - after all, these are still JBL?s! All jokes aside, with these, it is very easy to hear who has put forth a real effort in their work & who hasn?t, and that?s the reason for investing in a good set of monitors. I highly recommend them. I?ve mixed and mastered on several other monitors, but these are flat out the most functional I?ve ever had, let alone used. They also translate very well. At the end of the session, where the client doesn?t leave right away, but sits and listens to their recording in their vehicle on their ?monitoring system?, it?s all smiles!

      hear these before you buy

      Comments about JBL LSR4326P STU REF MON:

      My second set of studio monitors. If you are pricing a pair of monitors in the $600-$800 range these are worth the extra cash. The appearance exudes quality. Nice to look at, they sound as good as they look. Tight, clear and more watts than you will ever need. These are very nice for home recording.
