The JBL Control 1 Pro Plus is a compact two-way professional reference monitor designed for near-field listening in critical audio applications such as project studios, broadcast editing suites, and multimedia production environments. It builds upon the legacy of the classic Control 1 series, incorporating modern transducer and enclosure technologies to deliver accurate, detailed sound reproduction in a space-efficient format. The speaker employs a 5.25-inch polypropylene woofer for solid midrange and low-frequency response, paired with a 1-inch soft-dome tweeter for smooth high-frequency dispersion. This driver combination, coupled with a precisely tuned crossover network, is engineered to provide a flat, uncolored frequency response, making it suitable for audio evaluation, video post-production, and as a secondary reference system in professional settings.

Constructed with a dense, non-resonant MDF (Medium-Density Fiberboard) enclosure finished in a durable black vinyl wrap, the Control 1 Pro Plus is designed to minimize unwanted cabinet vibrations and coloration. The front baffle features a molded design that integrates waveguide principles to optimize the tweeter's dispersion and improve time alignment between the drivers, resulting in a stable, focused stereo image. The compact size allows for flexible placement on desks, stands, or shelves, and the cabinet is magnetically shielded as a standard feature to prevent interference with nearby video monitors—a critical consideration for integrated AV workstations.

While modest in size, this loudspeaker is engineered for professional reliability, capable of handling the dynamic peaks of mixed audio content. It is a passive design, requiring connection to an external amplifier or powered mixer, which offers system integrators flexibility in matching it with appropriate amplification. The JBL Control 1 Pro Plus is characterized by its articulate midrange, extended highs, and a surprising level of bass extension for its cabinet volume. It serves as a trustworthy and affordable tool for content creators who require a truthful acoustic representation of their work, offering a significant performance step above consumer multimedia speakers while maintaining the accessibility and ease of use that has defined the Control series for decades.
