The JBL Professional Control 227C is a premium in-ceiling professional loudspeaker designed for applications requiring superior quality sound in ceiling-mount applications. Delivering exceptional next-generation performance in a medium format coaxial point source design, the Control 227C incorporates breakthrough performance features such as best-in-class pattern control to provide a consistent sound throughout the listening area. Especially wide coverage allows fewer speakers to cover the space, reducing both the material and labor cost for the installation.
The Control 227C features a 6.5" Kevlar-reinforced low frequency driver coupled with a 1" exit titanium compression driver for enduring reliability and outstanding performance. An 8 ohm driver is utilized on the Control 227C and offers 150 Watts of continuous power handling capability.
The Control 227C is easy to install and features a removable multi-pin locking connector, with secure screw-down terminals. This allows the for pre-wiring the input wires for easy clip-on convenience during installation. The optional MTC-200BB6 14 cubic liter (0.5 cubic foot) back can is made of extra-thick 16 guage steel and the top is lined with 1/2" medium density fibreboard.
The clean, contemporary look of the MTC-RG6/8 grille for the Control 227C is designed to suit a variety of settings, offering a simple, elegant appearance that fits into a wide variety of décors.
To ensure long life and reliability, Control 227C passes JBLʼs 100-hour torture power test. Nobody in the industry has more demanding reliability standards.

In-Ceiling Audiophile Magic RC60i's round profile looks just like a lighting fixture so it will blend into your ceiling without calling attention to itself. But they sound sooooo much better than your typical in-ceiling speakers that resemble a watering spout. RC60i Features: - Easy one-cut, drop-in installation puts built-in audio within reach, with Perfect Fit templates, a precision flange, and (available) pre-construction brackets.
- RCi speakers utilize the "virtual enclosure" of your in-wall and in-ceiling space to enhance their bass response and smooth low frequency blending with the midrange.
- Lightweight and stiff blue polymer cones deliver excellent damping and bass response.
- Durable, computer-modeled, injection-molded butyl rubber surrounds suppress unwanted cone resonances for a lifetime of reliable sound.
- Aimable swivel tweeters for greater accuracy and more realistic imaging. (All models except RC6s.).
- Rustproof stainless steel hardware, durable butyl rubber surrounds and powder coated aluminum (in-ceiling) & painted steel (in-wall) grilles make RCi Series speakers suitable for high moisture areas like bathrooms or even under eaves of an enclosed porch. (RCi series are not suitable for exposed outdoor use).
- RCi speakers have paintable grilles and practically disappear into any room.
- RCi Series speakers are timbre-matched to other Polk speakers to insure utterly seamless blending from speaker to speaker in systems that combine traditional and built-in speakers.
