SoundTube Entertainment IW31-EZ-BK Overview

The black IW31-EZ In-Ceiling Speaker from SoundTube Entertainment is a 3” in-wall speaker for applications requiring 8Ω impedance or distributed audio solutions. The speaker incorporates a low-profile grille with a total visible footprint of 5 in2 and an integrated backcan and driver design for compact installations in wall plates.

The in-wall speaker includes a 6-position tap switch with a voice coil direct position. It also includes mounting hardware and features a fast and secure constant-tension SpeedWing mounting system. All components in the speaker are completely weatherized for indoor and outdoor applications.

Engineered for easy installation and low-profile mounting for smaller venues, this in-ceiling speaker is suitable for retail, restaurants, conference rooms, educational facilities, transportation hubs, correctional facilities, or any setting where full-range intelligibility, low-profile design, and in-wall installation ease are paramount. For additional bass response down to 41 Hz (- 10 dB), the SM1001p powered 10” subwoofer (available separately) may be incorporated.
