The ultra-flat UP W8BMW-S subwoofers are playing extremely dynamically and punchy. Especially the exceptionally rigid fiberglass cone generates maximum sound pressure without distortions.
The BMW-specific baskets and connectors allow fast and easy installation into the original mounting positions of all BMW model ranges with under-seat subwoofers.
Nevertheless these subwoofers are also perfectly qualified for universal applications. Thanks to the very low mounting depth, extremely compact sealed enclosures are no problem at all whereas the oversized 1.7” / 42.5 mm voice coil assures high power handling. With their 1 x 2 Ohms single voice coil the UP W8BMW-S are the perfect replacement for the original subwoofers of the BMW HiFi sound system. Additionally they are the perfect playmate for our MATCH Upgrade amplifier MATCH UP 7BMW and MATCH UP 7DSP.
No matter if these subwoofers are used for a bass upgrade in your BMW or as supplier of low-frequencies in universal concepts, they will definitely add loads of powerful bass for musical enjoyment.
