Typically, studio monitors are either known for its looks or its features, but rarely both. JBL 4350B, however, is different! The drop-dead looks and esoteric finish belies the studio monitor's capability to serve as a high-end device for attaining wide-band linear response, high acoustic output, and controlled dispersion.

Seated in a lightweight and rigid acoustic enclosure, the JBL 4350B is complemented by two 15-inch low frequency transducers, 12-inch midrange loudspeaker, high frequency compression drivers, diffraction horn, and other components that not only control the smooth reproduction of sound waves, but also prevent the dispersion of high frequency and catalyze transient performance.

Since the midrange and low frequency drivers are housed in separate sub-chambers, the interference/ resonance is minimized, and uniform system response is reached. The high and ultra-high transducers are installed as mirrored components. The enclosure also plays host to front-loaded user controls on the baffle panel.

With 4350B, JBL has created the ultimate tool for mixing master tapes, analyzing control room influences, relegating complex sonic effects to its appropriate channels, and fixing undesirable sound effects. As such, this wonder box is capable of wide dynamic range, low distortion, and high acoustic output.

JBL 4350B is a four-way monitor system with two amplifiers (bi-amp) designed for evening out distortions at peak volumes. The super-acoustic design prevents standing waves and internal reflections from adulterating the response mix.

Installed in the ported sub-chamber, two independent low frequency drivers act as the agents for precise reproduction of low frequencies and power handling. These drivers are ably supported by a 4-inch fabricated voice coil and magnetic assembly, which helps in reducing second harmonic distortions to zilch. Ditto with the midrange speakers, except that these drivers cater to frequencies between 250 Hz and 1.1 kHz.

Then there are the high and ultra-high frequency transducers each assigned with the responsibility of reproducing the audio spectrum beyond 1.1 kHz. Again, the combination of magnetic structure, voice coil, and a large diaphragm produces transient response and dynamic range. A bunch of horns and lenses are used for controlled propagation of high frequency acoustic energy.

With so many transducers in play, it is necessary to attenuate and crossover different frequencies for processing by different drivers. Provisions made in the studio monitors for frequency attenuation include the ability to use either a JBL Electronic Frequency Dividing Network or other commercially available electronic crossovers and filtering devices.
