Dependable Coverage, Signature JBL Sound
The JBL Control 400 Standard Coverage Series brings high-performance JBL audio to everyday commercial installations. The Control 414C/T Micro Plus pairs a coaxially mounted 4-inch woofer and 0.5-inch soft-dome tweeter in a low-profile enclosure and can be used in shallow plenums where a standard backcan won’t fit. Delivering higher output than the standard Micro, a frequency range of 69Hz–25kHz carries articulate speech and detailed music alike, distributed across an especially broad 160-degree conical pattern for even coverage on- and off-axis. Power handling scales to the install, with a built-in 70V/100V multi-tap transformer for distributed systems and an 8-ohm direct mode for low-impedance runs. For retail floors, corporate campuses, and hospitality spaces with tight ceiling clearance that still demand higher volume, the Control 414C/T Micro Plus delivers the performance and dependability at the core of the Standard Coverage Series.

One family, three levels of coverage
The JBL Control 400 family spans three coverage tiers, allowing integrators to match acoustic performance to the demands of each installation. The Standard Coverage Series is the most versatile of the three, built to fit almost any room and ceiling. Single-driver full-range models keep things simple for speech and background music, while coaxial models add a dedicated tweeter for greater output and clarity. Compact low-profile Micro models round out the series, slipping into shallow plenums where a standard backcan won’t fit. Underneath that variety, every model shares the same installer-focused engineering: terminal covers with top and side cable entry and a captive dogear design that adapts to a wide range of ceiling thicknesses. A paintable full-face magnetic grille delivers a clean, bezel-free look, and every model includes a transformer that supports both 70V/100V and low-impedance operation.


Adaptable to any room
Whatever the space, the Control 400 Standard Coverage Series drops cleanly into nearly any commercial environment. Sweetwater’s installation technicians recommend the Control 400 Standard Coverage Series when a space needs dependable, great-sounding audio for everyday use. Its efficient driver design allows a well-planned layout to serve the room evenly, without gaps that would call for extra speakers. From corporate offices to classrooms, restaurants to retail, a Standard Coverage Series setup delivers dependable audio in every space.
