Built for Commercial Audio Installation
The Electro-Voice EVID-S8.2TB combines a paintable, fire-rated ABS enclosure with a zinc-plated, powder-coated grille. Connections through the wall-mounted bracket help conceal wiring, while removable locking Euroblock connectors support additional speakers on a distributed line. Its rotatable grille logo accommodates horizontal positioning, and the EVID-S range is designed to work alongside other EVID ceiling and in-wall speakers.
Paintable ABS Enclosure

Corrosion-Resistant Grille
A zinc-plated, powder-coated grille provides corrosion resistance as part of the speaker’s weather-resistant construction.
Concealed Wall-Bracket Wiring
Electrical connections pass through the wall-mounted portion of the mounting system, allowing wiring to remain hidden for a clean installation.
Quick-Attach Mounting
The ball-and-socket mounting system features quick attachment and detachment, with the support bracket integrated into the enclosure.
Locking Euroblock Connections
Removable locking 4-pin Euroblock connectors provide an additional connection option and support wiring to further speakers in a distributed line.
Protected Bypass Selection
A rear-panel switch selects transformer taps or 8-ohm bypass operation. The bypass selection is protected by a safety screw.
