Description
The IW31-EZ-BK is a compact 3 inch in-wall full-range speaker designed for 8 ohm or distributed audio systems. It provides clear mid and high frequency reproduction between 190 Hz and 14 kHz and a shallow backcan for tight installations. The grille and enclosure are weatherized for indoor and protected outdoor locations.
Key features include a 3.0 inch polypropylene driver with a butyl rubber surround, a six-position tap selector with transformer bypass, and a corrosion-resistant powder-coated aluminum grille. The SpeedWing mounting system secures the speaker to wall thicknesses from 0.1 inch to 1.5 inch and enables fast blind-mount installation. Components are treated for indoor/outdoor durability and UL/CE compliance.
Performance metrics show an 85.5 dB sensitivity measured at 2.83 V/1 m and a max continuous RMS power rating of 20 W with 40 W program capacity. Frequency response is specified at 190 Hz to 14 kHz (-3 dB) and extends to 115 Hz to 22 kHz (-10 dB). Maximum SPL at 1 meter is 98.5 dB, and the directivity factor is listed as 4.5 averaged 100 Hz to 10 kHz.
Connectivity is via hardwired input leads and the unit accepts either 8 ohm direct-drive or a transformer option for 25/70.7/100 volt distributed systems. A conduit connector is included for protected wiring entries and the unit ships ready for standard audio installations. Optional accessories include a pre-construction bracket, theft-resistant grille, and compatible powered subwoofer for extended low-frequency output.
Typical applications include background and foreground music in retail, hospitality, and corporate environments where low visual profile and reliable sonic coverage are required. The shallow backcan and small visible footprint make the speaker suitable for retrofits and new construction alike. It integrates cleanly into zoned audio systems and paging infrastructures.
Installation is straightforward – the integrated backcan, driver and baffle simplify fit and alignment while the SpeedWing clamps hold the assembly securely during wall mounting. The grille snaps on for a low-profile 5 inch square visible footprint and is paintable for aesthetic matching. UL 1480 and 2043 approvals support use in many commercial installations and the product includes basic wiring accessories for quick deployment.
