JBL CSS-1S/T

Overview

The JBL CSS-1S/T is a pair of passive loudspeakers designed to deliver clear and balanced sound for indoor environments such as classrooms, retail shops, and cafés. Each speaker combines a 5.25-inch woofer with a 0.75-inch dome tweeter to produce audio that makes voices easy to understand and music sound full without distortion. With a maximum sound pressure level of 106 dB and a frequency response from 85 Hz to 18 kHz, these speakers provide ample volume and clarity for medium-sized rooms.

They feature a built-in 10-watt multi-tap transformer that supports 70V, 100V distributed audio systems, or an 8-ohm direct connection, offering flexibility depending on your amplifier setup. Installation is made simple with included wall-mount brackets, and the durable polypropylene enclosure allows for stable shelf placement as well.

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.
