2 1/2 way shallow profile speaker

The Sonodyne IWO 811 is a high-performance slim-profile installation speaker designed for applications that demand enhanced clarity, wider coverage, and stronger low-frequency presence in a discreet form factor. As part of the IWO 800 Series, it features an advanced 2.5-way design, making it ideal for premium residential, retail, and commercial audio installations.

Engineered with a 1-inch dome tweeter and dual 3-inch woofers, the IWO 811 delivers improved midrange detail and broader sound dispersion compared to standard 2-way designs. It is further enhanced by dual 3-inch high-compliance passive radiators, which extend low-frequency response and provide fuller bass without increasing cabinet depth—perfect for shallow wall installations.

With a power handling range of 60–100 watts and 8-ohm impedance, the speaker integrates easily with a wide range of amplifiers used in distributed audio systems. Its tall, slim enclosure ensures better vertical dispersion, making it suitable for spaces requiring consistent coverage across listening areas.

Designed for flexible installation, the IWO 811 includes a key-hole mounting system for quick on-wall setup, while an optional in-wall bracket (IWO WB 63) enables a clean, flush-mounted finish.
