Bring deep, controlled bass to your home audio system with the OSD Audio SMP200 and IWS8 in-wall subwoofer package.

-   **Space-Saving Design:** Flush-mounted installation keeps the subwoofer hidden in the wall, freeing up floor space while maintaining premium sound quality.
-   **Adjustable Controls:** Fine-tune your bass performance with variable crossover and phase controls on the SMP200, ensuring seamless integration with your main speakers.
-   **Durable Build:** Both the amplifier and in-wall subwoofer are engineered for long-lasting performance with high-quality components.
