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.

Fits Cats not Dog size
Color: red&green
Sure these balls are cute, but most definitely not a dog size. I wouldn’t waste your money, unless you own a cat!

Not durable
Color: red&green
The description says for cats and dogs. My 6lb mini poodle tore it up in less than 40 minutes. The red one worked but the green one wouldnt even turn on. The indicator said it was fully charged but u plugged it in for a short time but nothing. I dont know if i can get a refund or not since the cover on the red one has been completely torn off. I dont recommend this product

This is an awesome toy for dogs and cats!
Color: red
This is such a cool toy for a dog or a cat. I bought it for my 28 pound Aussie doodle. She’s slightly laid up after an injury recently so I’m trying to come up with things she can play with in the house without excessive running. This totally keeps her engaged and she loves it. But I have to watch her because every once in a while she’ll just catch it and try and chew on the ball! But I’ve been sharing it with my neighbor who has a cat. She’s borrowing it today and her cat loves it too! It seems pretty durable overall but it certainly doesn’t want my dogs’s jaws trying to crack it into. You do hear a humming noise while it’s running but I think that’s to be expected. Mostly I just love how much it entertains both dogs and cats!!

So cute and entertaining to watch!
Color: pink
Bought for my miniature schnauzer. She didn’t know what to think at first but loves it now. It’s so much fun watching her play and keeps her busy! My dog isn’t much of a chewer and loves the movement/chase of this toy. Wouldn’t recommend for big dogs or chewers as there’s a plastic piece that can come off.
