    Choose by Room

    LiveInSmart guidance:

    • **IWO 912** — 2 way, bass-reflex on-wall/in-wall speaker. The largest IWO 900 shallow-profile speaker: two 6-inch woofers plus two passive radiators, mountable on the wall or in the wall.
    • **IWO 911** — 2 way, bass-reflex on-wall/in-wall speaker. An IWO 900 shallow-profile on-wall/in-wall speaker with two 5-inch woofers and two passive radiators.

    Components You'll Need

    A passive speaker: it needs an AV receiver or power amplifier. A subwoofer is recommended for films.

    Installation Considerations

    Applies to both models:

    • Decide on-wall or in-wall before the wall finish is done
    • Plan speaker cable routes inside the wall or conduit
    • Keep left and right at the same height and distance from the screen
    • Add a subwoofer for films
