JBL Professional Control® 40 Series In-Ceiling Loudspeakers Earn UL Listing

JBL announced today that all five models in its Control® 40 Series of in-ceiling loudspeakers have earned a UL listing under UL1480 and UL2043. The increasingly vast JBL lineup of UL listed in-ceiling loudspeakers provides systems integrators with a variety of options for applications requiring UL listed products.

We introduced the Control 40 Series last year as the systems integrator's go-to speaker line for a wide variety of everyday premium applications," said Rick Kamlet, Senior Director, Commercial Installed Sound, JBL Professional. ³Now having earned its UL listing, the Control 40 Series joins the Control 24/26/19, the Control Micros, Control 200 Series and the Control 300 Series as a broad lineup of UL listed in-ceiling loudspeaker choices for designers and installers."

The Control Contractor 40 Series features JBL¹s proprietary Conical Radiation Boundary Integrator (RBI), adapted from JBL¹s groundbreaking VERTEC® series line array loudspeakers. This unique in-ceiling innovation combines a large-diameter, high-frequency waveguide and low-frequency projection apertures that work together to provide extremely consistent pattern control and coverage.

The Control 47C/T provides extended bass performance with a wide 120 degrees of coverage (consistent over a wide bandwidth) that allows fewer speakers to cover a large space. The Control 47LP is a low-profile version for areas with shallow clearance above the ceiling, or where there are obstructions is some locations. The Control 47HC is a narrow coverage model for difficult acoustic spaces and high-ceiling areas. Rounding out the lineup are the Control 40CS/T, a subwoofer with built-in passive crossover, and the Control 42C, an ultra-compact, in-ceiling satellite loudspeaker.
