We tested the JBL LSR6332L passive studio monitor!

Following acoustic measuring of an approximately of 18 square meters sound recording and mixing studio in Budapest, we performed the appropriate acoustic treatment. Sound-absorbing and diffuser panels were mounted on the walls as well as on the ceiling. We laid an acoustic carpet on the hard tile floor, making the studio surround sound absolutely perfect. In the case of sound recording or dubbing studios, it is even more important to have flawless acoustics, since the recorded sound in a room with echoes shall lead to a disappointing end result. Although, it is possible to slightly correct the acoustic errors with sound optimisation technologies, we cannot be completely satisfied. Therefore, the acoustic treatment of this type of rooms is unavoidable for all professionals. Thus we tested the JBL LSR6332 passive studio monitor in a perfect surround environment.

Introducing the JBL LSR6332L speaker

The 3-way, passive speaker has a power of 150-1000 Watts, frequency transmission 60Hz-20kHz, maximum sound pressure 112 dB, crossover frequency 250 Hz-2.2 kHz, impedance: 4 Ohms, speaker weight 20.4 kg. Unlike active speakers, passive speakers do not have a built-in amplifier, so for those who choose the passive type, they need to get an external stereo amplifier that can be connected to the speaker. The dual-coil Neodymium Differential Drive subwoofer increases performance and reduces distortion. The mid-speaker neodymium, magnetic Kevlar cone, and titanium composite tweeter result in excellent linearity, high resolution, and low distortion. When recording or mixing audio, it is a great advantage that the JBL speaker uses LSR (Linear Spatial Reference) technology to broadcast the sound in real, detail and accuracy.

JBL LSR6332L review

It can also be used as a reference or main monitor, thanks to the precise design. The frequency transmission is completely optimal, the recording is balanced, the sound image is clear and detailed. The dense baffle and reinforced casing ensure stability and reduce to minimum resonance of the housing. Linear Dynamics Aperture prevents turbulence. It can easily cope with high sound pressure. Compared to its predecessors, the JBL LSR6332L has a great new feature. Room Mode Compensation makes it possible to eliminate interference in the range below 100 Hz, taking into account the characteristics of the rooms.

On a musical journey

Since the speakers were installed in a recording studio, we focused our tests primarily on music. We tried to listen to as many different genres as possible. We listened to Michael Jackson’s marathon-length, sensational hit Smooth Criminal. Upon hearing the unique singing voice of the king of pop, the fantastic rhythms and music, we all felt the urge to dance. But we decided to ignore the rhythm to concentrate to the task at hand. The JBL provided a really lifelike and spacious sound, we got nice bass tones and pleasant mid and high ranges. Each sound of the song was detailed and clearly separable. The speakers performed to the high expectations of the king of pop. The pop was followed by classical music. We played one of the wonderful and well-known classical pieces by Haydn the Cauldron Drum Symphony‘s second part. The speaker, paired with a good quality amplifier, sounded without distortion even at high volumes, we heard the instruments as if we were in a live concert room. We experienced similarities while listening to Beethoven’s Moonlight Sonata. Every beat and rhythm sounded in perfect harmony.

Freddie Mercury

Since the show went on, we put on Freddie Mercury’s song The Show Must Go On. The unforgettable hit touched our souls again, and the sound flowed evenly in the room covering the whole space, creating a real sense of spaciousness.

The last performer of our reminiscent musical adventure featured the song Bella Ciao from La Casa De Papel. The remake of the originally Italian folk song became popular as the soundtrack of the popular series. JBL did not disappoint, again, our assessment was entirely positive.

Our opinion

We can only mention advantageous features of this great studio monitor, no flaws to report about. We recommend it mostly for sound mixing and sound recording professionals. For hobby purposes, it is worth choosing hi-fi speakers with an active built-in amplifier. In the case of passive monitors, it does not hurt to have some expertise in the field of audio, so that we can find the right amplifier and set it up. The American dream, the JBL LSR6332L, will do an excellent job in a studio with optimal acoustics.
