JBL CONTROL 19CST

Overview

The JBL CONTROL 19CST is a pair of in-ceiling subwoofers designed to deliver powerful bass while preserving floor and wall space. Each subwoofer features an 8-inch polypropylene woofer capable of handling up to 200 watts of program power, producing low-frequency sound from 42 Hz to 200 Hz. These subs are ideal for commercial environments like restaurants, offices, and retail spaces where subtle yet impactful bass enhances the audio experience without visible hardware.

With a built-in multi-tap transformer, the subwoofers integrate easily into 70-volt or 100-volt distributed audio systems. The design includes a Nested Chamber and ported enclosure that extends bass response without increasing the size of the unit. Finished in white and paintable to blend with ceilings, the CONTROL 19CST subs come with mounting hardware and connectors for a streamlined installation process. Their UL rating for air-handling spaces makes them suitable for a wide range of commercial applications.

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.
