MATCH MW 8 BMW-D Sub Woofer

MATCH MW 8BMW-D

The MW 8BMW-D subwoofers are not only the ideal upgrade for those who are dissatisfied with the bass response in their BMW, but particularly for  those who want to realize unprecedented space saving installation concepts.

The BMW-specific baskets and Plug & Play connectors allow a 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.

Furthermore, the special speaker connector with its gold-plated screw terminals allows two different configurations. If the metal bracket is mounted the woofer has an impedance of 1 x 4 Ohms - without the metal bracket each voice coil can be driven separately (in this case 2 x 2 Ohms) which is perfect  for the combination with MATCH Plug & Play amplifiers.

No matter if these subwoofers are used as bass upgrade in your BMW or as problem-solver in small sub enclosures, they will definitely add loads of powerful bass for musical enjoyment.

Features

• 8” subwoofers with very low mounting depth for shallow subwoofer designs and under-seat installation in BMW vehicles

• Allows to use extremely compact, sealed enclosures

• Oversized 42.5 mm / 1.7” voice coil for high power handling

• 2 x 2 Ohms impedance per woofer for most flexible connection options

• Plug connectors for original BMW cable harness are included in delivery

• Fits directly into the original mounting positions under the front seats of all BMW model ranges with under-seat subwoofers

• Also ideal for universal use in ultra-flat subwoofer constructions

The speaker connector with its gold-plated screw terminals allows two different configurations. If the metal bracket is mounted the woofer has an impedance of 1 x 4 Ohms. Without the metal bracket each voice coil can be driven separately (impedance in this case 2 x 2 Ohms) which guarantees a perfect interaction with MATCH Plug & Play amplifiers.
