Key Configuration

Model: CBS240 | Capacity: 5 W maximum power at 8 ohm impedance | Driver: 4" polypropylene cone | Connectivity: 10 ft cable with 3.5mm miniature plug | Protection: All-weather; black ABS plastic enclosure with stainless steel hardware

Key Features

• • All-weather construction for marine and outdoor communications use.
• • 4" polypropylene cone.
• • Stainless steel hardware resists corrosion.
• • 180 degree adjustable mounting bracket.
• • 10 foot cable with 3.5mm miniature plug included.

Technical Context

A polypropylene cone resists the moisture absorption that degrades paper-cone drivers in marine and exposed positions, and the stainless steel hardware avoids the corrosion that plated steel suffers in salt air. The 8 ohm, 5 W rating suits it to communications and paging duty as an extension speaker rather than to full-range music reproduction.

Installation Notes

The speaker ships with a 180 degree deluxe adjustable bracket, allowing the output to be aimed after mounting. A 10 foot cable terminated in a 3.5mm miniature plug is included, so the run to the source is fixed at that length unless extended. The unit is sold individually rather than in pairs. Physical dimensions are not published — the linked specification sheet should be checked before committing to a mounting position.
