Bosch Audio EVID-EC4.2 2-way Coaxial In-ceiling Speaker

Product Description

The BOSCH AUDIO EVID-EC4.2 is a 4-inch 2-way coaxial in-ceiling loudspeaker designed for commercial and professional audio distribution applications. The coaxial driver configuration places the tweeter concentrically within the woofer, producing a unified acoustic center and consistent coverage pattern across the listening area. This speaker is sold as a single unit and is installed by audio-visual integrators, low-voltage contractors, and commercial electricians as part of distributed sound systems in facilities requiring ceiling-mounted audio coverage.

The EVID-EC4.2 fits in-ceiling installations where a compact 4-inch form factor is required. Typical deployments include conference rooms, corridors, retail environments, hospitality spaces, and light commercial facilities. The speaker integrates into distributed audio systems driven by low-impedance or 70-volt amplifier infrastructure, depending on system design. Its ceiling-mount format allows flush integration into standard drop or hard-lid ceilings with minimal visual footprint.

Key Features

• 4-inch 2-way coaxial driver for unified acoustic center and broad coverage
• In-ceiling mounting format for flush, low-profile installation
• Compact form factor suited to small and medium commercial spaces
• Single-unit packaging for straightforward per-location deployment

Compatibility

Designed as an OEM-style replacement or new-installation component for in-ceiling distributed audio systems requiring a 4-inch coaxial loudspeaker in commercial or light commercial environments.

Installation Notes

Installation should be performed by a licensed low-voltage contractor or qualified audio-visual integrator in accordance with applicable NEC low-voltage wiring requirements. De-energize the amplifier and any associated power sources before making speaker connections or cutting ceiling openings. Use the appropriate hole saw for the required cutout diameter and verify ceiling plenum ratings if wiring runs through a return-air plenum. Do not exceed the amplifier channel power rating for the number of speakers wired in parallel.
