About the JBL CONTROL 47LP Two-Way 6.5” Coaxial Low-Profile Ceiling Loudspeaker
The JBL CONTROL 47LP is a low-profile, two-way coaxial ceiling loudspeaker engineered for high-quality audio reproduction in commercial and residential distributed sound systems where a shallow installation depth is a critical requirement. This model integrates a 6.5-inch low-frequency driver with a concentrically mounted 0.75-inch soft-dome tweeter, creating a coherent point source that delivers wide, uniform sound dispersion and excellent off-axis response. Its primary application is in spaces with limited plenum depth, such as concrete slab ceilings, retrofitted rooms, and modern buildings with minimal overhead clearance, where traditional deeper speakers cannot be installed. The speaker provides a balanced, full-range output suitable for background music, paging, and audio reinforcement in offices, retail stores, restaurants, and upscale residential settings.
The coaxial design ensures that the high and low-frequency sound originates from the same acoustic point, which eliminates phase cancellation issues and provides a consistent frequency response across a broad listening area. This results in clear, intelligible audio with a well-defined stereo image, even for listeners positioned away from the speaker's central axis. The loudspeaker is equipped with a built-in multi-tap transformer, offering seamless compatibility with standard 70.7V/100V constant-voltage amplifier systems commonly used in commercial installations, as well as a direct 8-ohm mode for simpler low-impedance applications. This flexibility allows for easy integration and precise power matching within diverse audio system designs.
Installation is simplified by the speaker's exceptionally shallow back-can design and an integrated, tool-free mounting system. The chassis features a quick-connect terminal block for easy wiring and a magnetic, paintable grille that sits nearly flush with the ceiling surface for a discreet, finished appearance. The overall construction is robust, utilizing durable materials suitable for plenum environments. By combining coaxial sonic performance with a genuinely low-profile form factor, the JBL CONTROL 47LP provides an effective and unobtrusive audio solution for achieving high-fidelity sound in space-constrained architectural environments.
