The JBL Control 28-1L is an 8-inch two-way foreground loudspeaker designed for high-fidelity sound reproduction in commercial background music and foreground paging applications. This compact yet powerful speaker integrates a robust 8-inch low-frequency driver and a precision 1-inch titanium dome compression driver, coupled with a waveguide-loaded horn for controlled dispersion. The system is engineered to deliver articulate, full-range audio with clarity and sufficient output for spaces such as retail stores, restaurants, corporate lobbies, and hospitality venues where both music playback and clear speech announcements are required. Its durable construction and moisture-resistant components make it suitable for both indoor and semi-protected outdoor installations.

A key feature of the Control 28-1L is its integrated 70V/100V multi-tap transformer, which simplifies installation in distributed sound systems by allowing multiple speakers to be connected over long cable runs from a single amplifier. This transformer includes multiple power tap settings, enabling installers to balance audio levels across a zone precisely. The speaker's enclosure is constructed from UV-resistant, mineral-filled polypropylene, ensuring long-term stability against environmental factors and physical impact. The integrated bracket and multiple mounting points offer flexible installation options, including surface mounting, wall mounting, or pendant mounting with an optional accessory.

The acoustic design prioritizes consistent coverage and sonic accuracy. The waveguide horn provides a wide, even dispersion pattern, minimizing "hot spots" and ensuring uniform sound distribution throughout the listening area. The speaker's voicing is tailored for commercial use, offering a balanced sound that remains clear and intelligible even at lower volume levels. As part of JBL's renowned Control Contractor series, the Control 28-1L represents a reliable, scalable solution for integrators and installers needing a versatile, high-performance speaker that delivers professional audio quality in a wide range of commercial sound reinforcement scenarios.
