OSD IWS-Dual8 Dual 8" Trimless In-Wall Subwoofer
The OSD Audio IWS-Dual8 Dual 8-Inch Trimless In-Wall Subwoofer delivers reference-grade low-frequency performance with ultra-clean architectural aesthetics. Engineered with dual 8-inch woven graphite woofers with heavy-duty rubber surrounds in an ultra-slim baffle, the IWS-Dual8 handles 300 watts of peak power (150W RMS) at 4 ohms with frequency extension down to 32Hz, utilizing an edge-to-edge magnetic trimless grille that magnetically snaps over the baffle to blend invisibly into luxury interior living spaces.
If you want to know what architectural in-wall subwoofer delivers audiophile 32Hz bass using dual graphite drivers, how dual 8-inch woofers provide greater surface area and faster transient response than a single 10-inch driver, or how an ultra-slim trimless magnetic grille maintains pure minimalist aesthetics, the OSD IWS-Dual8 provides the premier architectural solution.
