Harmony HR 11 SW — 11"/280 mm Spare Wheel Amplified Subwoofer | HF Audio
Harmony HR 11" spare wheel active sub. The stealth install solution for OEM spare tire wells.
Built for the Passionate. Engineered for the Road. The Harmony HR 11 SW is a spare wheel amplified subwoofer — a self-powered 11" active driver designed to mount directly in the spare tire well of vehicles where that space is otherwise unused. This is the cleanest possible stealth bass install: the trunk appears stock, but the system plays with genuine Italian bass extension. The circular form factor matches the geometry of the spare tire well in most sedans, hatchbacks, and compact SUVs. Self-powered with integrated crossover and bass level control. No enclosure to build, no trunk space consumed, no visible modification. The ideal solution for enthusiasts who prioritize OEM aesthetics and want genuine bass performance without compromise. Connect to any head unit. Pair with HB1.6K2X or HB1.6C front speakers for a complete, invisible Italian daily system.
