JBL CONTROL 28-1

Overview

The JBL CONTROL 28-1 is a pair of high output indoor/outdoor speakers designed to deliver clear background or foreground sound in a variety of settings. Each speaker features an 8-inch fiberglass woofer for solid bass and a 1-inch PEI tweeter that provides crisp detail to vocals and instruments. With a 100 by 100 degree dispersion pattern and the ability to handle up to 240 watts of amplifier power, these speakers fill wide areas evenly and maintain balanced sound quality for music and speech.

Built to withstand the elements, the weather-resistant enclosure and rubber-sealed edges protect the components from rain, sun, and wind, making them suitable for both indoor and outdoor use. The InvisiBall mounting system allows for precise aiming and secure installation with a discreet appearance, while the paintable black finish helps the speakers blend seamlessly into any décor.

The wide dispersion pattern and high power handling also ensure they perform well with a variety of amplifier setups.

Installation and setup

Installation is simplified by the InvisiBall mounting system, which allows you to secure the base and then adjust the speaker’s aim precisely before locking it in place. This system keeps mounting hardware out of sight, maintaining a clean and professional look. The speakers’ paintable finish offers flexibility to match any environment, whether indoors or outdoors.

These speakers are well suited to venues that require reliable, high-quality sound both indoors and outdoors. They work effectively in restaurants, theme parks, gyms, retail spaces, and backyard patios. Their weather-resistant design and robust power handling make them a strong choice for areas exposed to the elements or high foot traffic, while their balanced sound reproduction supports clear music and speech in both background and foreground roles.

We act solely as a reseller. Any product warranty is provided and administered by the manufacturer, not by our store. That means eligibility, coverage, and outcomes are determined by the manufacturer’s policy for each brand and model. Before purchasing, we recommend reviewing the warranty terms on the manufacturer’s website or in the product documentation to confirm what is covered and for how long.

If you need warranty service, please file the claim directly with the manufacturer. They may require proof of purchase, the product serial number, original packaging, photos, or basic troubleshooting. Some brands ask you to register the product or obtain a case number before shipping it for repair or replacement. We don’t submit or approve claims, but we can point you to the correct support links and contact details.

Keep your invoice and packaging in a safe place, and report any functional issues to the manufacturer as soon as they appear. If you’re unsure whether a problem is covered, the manufacturer’s support team can confirm next steps and timelines. While we cannot intervene in decisions or outcomes, we’re happy to provide purchase documentation or guidance so you can move through the warranty process smoothly.
