MATCH UP W8BMW-S - Subwoofer da 20 cm / 8 " slim

.

Maximum POWER for BMW audio concepts

The ultra-thin UP W8BMW-S subwoofers deliver powerful, dynamic sound. Their highly rigid fiberglass diaphragm generates maximum sound pressure without distortion.

Thanks to BMW-specific speaker baskets and connectors, they can be quickly and easily installed in the factory-fitted enclosures on all BMW models equipped with an under-seat subwoofer.

These subwoofers also offer ideal conditions for universal use. Their exceptionally shallow installation depth allows for use in extremely compact, sealed enclosures. The oversized 42.5 mm voice coil ensures high power handling. With its single 2 ohm voice coil, the UP W8BMW-S is the perfect replacement for the woofers in BMW HiFi audio systems and can be optimally paired with the MATCH UP 7BMW amplifiers and, for universal vehicle applications, with the UP 7DSP.

Whether you're boosting the bass in your BMW or providing low frequencies in universal applications, nothing stands in the way of enjoying music with just the right amount of bass.
