The JBL Control 28 is a compact, high-performance two-way loudspeaker designed for professional background music, foreground music, and vocal reproduction in a wide range of installed commercial sound applications. As a member of the renowned Control series, it is engineered for durability and consistent sonic performance in both indoor and outdoor environments. The speaker utilizes an 8-inch mineral-filled polypropylene woofer paired with a 1-inch soft-dome, ferrofluid-cooled tweeter, a combination optimized for delivering clear, intelligible sound with robust bass response relative to its cabinet size. Its design prioritizes broad, even dispersion and high power handling to ensure reliable coverage in acoustically challenging spaces such as restaurants, retail stores, hotels, and transportation hubs.

The enclosure is constructed from ultra-violet resistant, impact-modified ABS plastic, making it highly resistant to weather, chemicals, and physical abuse, which qualifies it for demanding outdoor installations. A fully sealed design with an integrated grille protects the drivers from moisture, dust, and incidental contact. The speaker is offered in a neutral white or black finish to facilitate aesthetic blending with various architectural styles. For mounting flexibility, it features an integrated U-bracket that provides 90 degrees of vertical tilt adjustment, along with multiple threaded inserts that allow for alternative mounting solutions, including pendant and wall-attached configurations.

Intended for use with external amplifiers, the Control 28 is compatible with both low-impedance (8-ohm) and 70V/100V constant-voltage distribution systems, thanks to its built-in multi-tap transformer. This versatility makes it a staple for audio contractors designing distributed sound systems where consistent performance and installation ease are paramount. Its sonic character is characterized by a balanced frequency response with exceptional vocal clarity and enough low-end presence to provide full-range music reproduction without requiring an external subwoofer in many applications. The JBL Control 28 represents a benchmark for reliability and performance in the commercial loudspeaker category, trusted for its consistent output and ability to perform reliably for years in varied environmental conditions.
