MATCH MW 8BMW-D - Subwoofer da 20 cm / 8 " slim

.

The MW 8BMW-D subwoofers are not only the ideal solution for boosting the bass of those who are dissatisfied with the low-frequency reproduction in their BMW, but also for those who want to create extremely compact installations within their vehicle.

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

These subwoofers offer ideal conditions for universal use. Their exceptionally shallow installation depth allows for installation in extremely compact sealed enclosures. The oversized 42.5 mm voice coil ensures high power handling. Furthermore, the special connection terminal with gold-plated screw terminals allows for two different configurations, offering maximum connection flexibility. With the included metal jumper installed, the subwoofer has an impedance of 1 x 4 ohms. Without a jumper, each voice coil can be controlled individually (2 x 2 ohm impedance), allowing for optimal integration with MATCH Plug & Play amplifiers.

Whether 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.
