Match UP W8BMW-S - 20cm subwoofer

Description:

Maximum POWER for BMW sound concepts

The super-flat UP W8BMW-S subwoofers play powerfully and dynamically. The highly rigid fiberglass membrane in particular generates maximum sound pressure while remaining distortion-free.

Thanks to the BMW-specific loudspeaker baskets and connectors, quick and easy installation in the factory-provided installation locations of all BMW model series with under-seat subwoofers is possible.

But these subwoofers also offer ideal conditions for universal use. The particularly low installation depth enables use in extremely compact, closed housings. The oversized 42.5 mm voice coil guarantees high resilience. With its 2 ohm single voice coil, the UP W8BMW-S is the perfect replacement for the bass speakers of the BMW HiFi sound system and can be optimally combined with the MATCH upgrade amplifiers UP 8BMW and the UP 8DSP for universal vehicle concepts.

Whether as a bass upgrade in your BMW or as a low-frequency supplier in universal applications, nothing stands in the way of enjoying music with the right amount of bass.
