Jbl Professional CSS800 4 In-ceiling 70V Dual Cone Speaker

Product Description

The JBL PROFESSIONAL CSS800 4 is an in-ceiling dual cone speaker designed for 70V distributed audio systems. It delivers background music and paging audio in commercial and light commercial environments where a low-profile ceiling installation is required. The dual cone driver design supports consistent sound dispersion across a wide listening area. Licensed audio contractors and low-voltage installers are the primary trades who specify and install this unit in new construction and retrofit applications.

The CSS800 4 is suited for 70V constant-voltage distributed speaker systems commonly installed in restaurants, retail spaces, offices, and similar commercial venues. It mounts flush in a standard ceiling grid or drywall ceiling. The 70V line configuration allows multiple speakers to be wired in a series-parallel arrangement over long cable runs without significant signal loss, which is the standard method for commercial audio distribution.

Key Features

• Dual cone driver design for broad sound dispersion in ceiling applications
• 70V line compatibility supports long-run commercial distributed audio wiring
• In-ceiling form factor for low-profile, flush-mount installation
• Sold as a single unit per package

Compatibility

Designed as an OEM-style replacement or new-install component for 70V constant-voltage distributed audio systems in commercial in-ceiling speaker applications.

Installation Notes

Installation should be performed by a licensed low-voltage or audio contractor familiar with 70V distributed speaker systems. Power down the amplifier and verify zero voltage on the line before making speaker tap connections. Follow NEC Article 640 guidelines for audio signal wiring in commercial occupancies. Do not exceed the tap wattage rating of the transformer when setting the impedance tap on the speaker.
