2 1/2 way, vented on-wall/in-wall speaker

The Sonodyne IWO 812 is the top-tier model in the IWO 800 Series, engineered for high-performance installations that demand powerful output, extended bass, and wide coverage—all within a sleek, shallow-profile enclosure. Designed for premium residential and commercial applications, it delivers room-filling sound while maintaining a clean, minimal visual presence.

Featuring an advanced 2.5-way design, the IWO 812 incorporates a 1-inch dome tweeter, dual 4-inch woofers, and dual 4-inch high-compliance passive radiators. This configuration provides enhanced midrange clarity, stronger bass response, and improved overall efficiency. The passive radiators extend low-frequency performance without increasing cabinet depth, making it ideal for in-wall or low-profile on-wall installations.

With a higher sensitivity rating of 88 dB and power handling up to 120 watts, the IWO 812 delivers greater output and dynamic range compared to smaller models—making it suitable for larger spaces and installations requiring higher sound pressure levels.

Its tall, slim form factor improves vertical dispersion and coverage, ensuring consistent sound distribution across listening areas. Installation is straightforward with the included key-hole mounting system, while the optional IWO WB 64 bracket allows for a flush in-wall finish.
