OSD Black SC800D 8" Sealed In-Wall Subwoofer with 10" Passive Radiator

The OSD Black SC800D 8-Inch Sealed In-Wall Subwoofer with 10-Inch Passive Radiator is a reference architectural bass system engineered with a fully sealed integrated MDF backbox enclosure. Combining an 8-inch long-throw carbon fiber active driver with a tuned 10-inch passive radiator, the SC800D handles 300 watts of continuous power at 4 ohms across 28Hz to 150Hz, delivering reference cinema-grade bass slam while completely isolating acoustic energy from adjacent rooms.

If you want to know what in-wall subwoofer delivers true 28Hz sealed-box bass without leaking sound into adjoining bedrooms or hallways, how a carbon fiber 8-inch active driver paired with a 10-inch passive radiator delivers the acoustic output of a 12-inch subwoofer, or how an integrated sealed MDF enclosure guarantees consistent acoustic performance regardless of wall cavity size, the OSD Black SC800D provides the pinnacle architectural solution. Audio purists and luxury home cinema designers specify the SC800D for uncompromising fidelity.
