The JBL 4301 is a compact monitor speaker designed for use in limited spaces, such as broadcasting stations and editing rooms. It features a 2-way, 2-speaker, bass reflex design with bookshelf-type enclosure, making it suitable for various audio settings. The low-frequency range is produced by a 20 cm cone-type woofer (model 116A), known for its rigid cone material that balances mass and compliance for optimal sound reproduction. The high-frequency sounds are generated by a 3.6 cm cone-type direct radiator (LE25-2), which incorporates a high-density foam surround to minimize distortion and enhance clarity. The speaker employs advanced engineering techniques, such as precise aluminum die-cast frames to prevent unwanted resonance and a large Alnico V magnetic circuit that contributes to the speaker's efficiency. The crossover design enhances phase characteristics and impedance correction to ensure a seamless audio experience. Additionally, the enclosure is crafted from high-density materials with a walnut finish, combining aesthetics with durability. The JBL 4301 operates with a frequency response from 45 Hz to 15 kHz, a nominal impedance of 8 ohms, and a maximum input power of 15W (RMS). Its compact design includes adjustable high-frequency level controls, providing versatility for different listening environments.
