About the 4355
The JBL 4355 Studio Monitor is a high-fidelity, four-way, five-speaker bass-reflex system designed primarily for large recording studios requiring high sound pressure levels. It features biamplification with two 15-inch 2235H woofers housed in a 265-liter bass reflex chamber tuned to 32 Hz, a 12-inch 2202H midrange driver in a sealed 48-liter sub-chamber, and horn-loaded high frequency drivers (2441, 2308, 2311) plus a 2405H ultra-high frequency driver. The system achieves a smooth frequency response from 28 Hz to 20 kHz, with crossover frequencies at 290 Hz, 1.2 kHz, and 10 kHz. It delivers a sound pressure level of 96 dB (290 Hz or less) and 99 dB (above 290 Hz), with a maximum continuous program SPL of 126 dB. The enclosure measures 1223 mm wide, 901 mm high, and 510 mm deep, weighing approximately 120 kg. The 4355 is renowned for its exceptional transient response, low distortion at high volumes, and controlled high-frequency dispersion, making it indispensable for mastering, mixdown, and detailed studio analysis. It was produced around the early 1980s and remains a sought-after vintage studio monitor.
