2 1/2 way shallow profile centre speaker

The Sonodyne IWO 821 is a slim-profile centre channel speaker designed for on-wall or in-wall installations where clear dialogue, balanced sound, and minimal visual impact are essential. As part of the IWO 800 Series, it is optimized for home theater systems, delivering focused vocal clarity and seamless integration with left and right channel speakers.

Built with a 2.5-way design, the IWO 821 features a 1-inch dome tweeter, dual 3-inch woofers, and dual 3-inch high-compliance passive radiators. This configuration enhances midrange detail and dialogue intelligibility while extending low-frequency response—all within a shallow 3.7-inch enclosure.

The passive radiator design improves bass performance without increasing cabinet depth, making it ideal for modern installations where space is limited. With a power handling range of 60–100 watts and 8-ohm impedance, it pairs easily with AV receivers and multi-channel audio systems.

Designed for flexible installation, the speaker includes a key-hole mounting system for easy on-wall setup, with an optional IWO WB 63 bracket available for flush in-wall mounting. Its horizontal form factor ensures wide sound dispersion, delivering consistent dialogue across the listening area.
