Atlas Sound IWM820 – 8" 2-Way 65W In-Wall Speaker Pair (Black)

Product Overview

The Atlas Sound IWM820 is an 8-inch 2-way in-wall speaker pair delivering 65W RMS at 8 ohms with a frequency response of 40 Hz–24 kHz. Designed for residential and light commercial in-wall speaker installations, the IWM820 produces high-fidelity background music and home theater audio without occupying floor or shelf space. The polypropylene cone woofer, rubber surround, and PEI balanced dome tweeter combination provides accurate, full-range sound reproduction suited for in-wall audio installations in living rooms, bedrooms, and commercial hospitality spaces.

Product Description

Sold as a matched pair, the IWM820 is part of the Atlas MUSICA series, engineered to integrate into wall cavities while delivering audiophile-grade sound at an accessible price. The 8-inch polypropylene woofer with rubber surround provides reliable low-frequency extension to 40 Hz, while the 12mm PEI balanced dome tweeter handles high-frequency reproduction up to 24 kHz for natural, uncolored audio. A 6 dB/octave woofer crossover network ensures a smooth handoff between drivers. The collared dog leg mounting system simplifies single-person installation—the collar locks the speaker against the wall without requiring access from behind the drywall. Press-fit, low-profile aluminum grilles are paintable, enabling the speaker to disappear into any wall color scheme. Debris-resistant speaker baskets protect the drivers from dust and particles that enter through the wall cutout. At 90 dB sensitivity (2.83V/1m), the IWM820 reaches adequate listening levels from modest amplifier power, making it compatible with most multi-room audio systems and distributed audio amplifiers. The 9.90" x 13.92" face dimensions and 3.39" mounting depth fit standard stud-bay installations without special framing.
