Provide your commercial spaces with powerful 2-way sound and a sleek look with the Control 424C/T from JBL, a ceiling-mounted loudspeaker for plenum spaces with a 4" woofer and a coaxially mounted 0.75" soft-dome tweeter. With up to 240W peak power handling and JBL-exclusive CRBI tech for highly consistent coverage, this loudspeaker can handle a wide range of spaces.

The 30W multitap transformer supports 70 or 100V operation for distributed systems, or the transformer can be bypassed for direct, high-impedance 16-ohm operation. In 16-ohm mode the loudspeaker can be paralleled with up to four speakers (on a 4-ohm rated amp channel). The loudspeaker offers an extremely wide 130° conical coverage angle, which when combined with the CRBI tech, allows you to use fewer speakers in installations. Connectivity is via 2-pin block connectors, and the dog-ears sport top and side cable entry options for a flush look. Stylish and refined, this subwoofer is designed to fit well in modern spaces and features a magnetically attached bezel-free grille. An IP33 rating ensures solid protection from dust and light water sprays, enabling use in a wide range of environments. The Control 424C/T includes a white rounded grille, a C-ring, and tile rails for fast installation.

Superior Sonic Performance
The Coplanar Radiation Boundary Integrator technology, or CRBI, delivers an especially smooth sound character that remains consistent, clear, and pleasant across a wide coverage area. It reduces on-axis hot spots and off-axis cold spots and improves the listening experience for users as they move throughout a space. This enhanced coverage results in fewer speakers, amplifier channels, and project costs required to cover a space.
2-Way Coaxial Drivers
The 4" low-frequency driver is acoustically loaded via the JBL-exclusive CRBI loading plate, increasing both efficiency and sensitivity for higher output. The CRBI’s unique L-contour radial apertures provide smooth low-frequency response and a tight, impactful sound.
A coaxially mounted 0.75" soft-dome tweeter provides high-fidelity sound character, with a neodymium magnet assembly and Kapton voice coil former providing durability. The drivers are designed for long-term reliability, and built-in protection circuitry helps to prevent damage from the occasional overload.
Versatile Configuration Options
The direct input’s high 16-ohm impedance allows connecting up to 4 speakers in parallel on a 4-ohm rated amplifier channel. For distributed systems, the transformer is designed for exceptionally low saturation, even at high drive levels, providing a top-quality, low-distortion distributed sound character.
The optimized ported enclosure delivers warm, smooth bass response. Low-frequency output can be further augmented with the addition of a Control 419CS/T or another Control Contractor subwoofer model.
Efficient and Flexible Installation
Various Control 400 Enhanced Coverage Series mounting enhancements improve installation repeatability and safety while reducing installation time. Redesigned terminal covers provide both top and side cable entry ports and can be secured without tools thanks to captive hand screws. The captive dog-ear design is extremely reliable and works with a wide range of ceiling thicknesses.
Refined, Modern Aesthetic
Full-face magnetic grilles provide a sleek, refined look to meet the sensibilities of modern architectural design. They are equipped with safety tethers, which mount right into the baffle to ensure peace of mind. Optional black and square accessory grilles are also available to empower added design versatility.

Easy install
Just installed in our bathroom. Feels solid. We have a potted plant on it now. You will want a drill bit extender to clear the shelf. I use the flexible type. Otherwise you won’t be able to get the screws in at a 90 degree angle.

Very nice, well made.
The nine-inch oak shelf is well made, and is 45 degrees. The wall where I planned to install it was not, and I suspect this is the problem some of the reviews saying the shelf was not made at 45 degrees. In my case, we removed wood a bit at a time until we achieved a good fit. We did receive all of the hardware, but beware. The plastic straight insert anchors do not snug up with the supplied screws. However we used the supplied plastic toggles with better results. The hardware is why I rate this 4 stars. Otherwise, it is a nice piece, and well worth the price.

Pieces missing, poor instructions, would not buy again!
Let's start with the good news: I did, eventually, get the shelves hung after a trip to the hardware store and some trial and error. Now for the bad news: * One of the screws holding the brace to the shelf was missing, making the shelf wobbly before I even hung it. * The directions for hanging the shelves show a different anchor than the one that comes packaged with them. This anchor will ONLY work in sturdy drywall and it's going to leave a huge hole behind. * The directions tell you to flip the shelf upside-down to position and mark the screw holes, BUT that means the sides of the shelf are reversed, and the hole positions do not match on each side. So if you start hammering or drilling based on those marks, they don't align and now you have extra holes in your wall. Honestly, I regret buying these and wish I'd just chosen a free-standing shelf instead. But I made it work for me, so I guess there's that.
