K 10E.2


Compact in size, but really fat in sound. The K Series enclosure subwoofers know no mercy when it comes to inspiring you with powerful beats.

Clever downfire case construction

So that both friends of maximum sound pressure and demanding music lovers get their money's worth, these housing subwoofers bring various technical refinements with them. The construction of the downfire subwoofer is designed to use the floor as a reflection surface. It also enables a flatter design, so that it can be accommodated under the double floor in the trunk to save space.

Technically sophisticated

A hard-hitting membrane made of hand-made paper fibres, in conjunction with heavy-duty voice coils, converts the amplifier output effortlessly and without compression effects into maximum punch, without missing the necessary sensitivity.

Flexible connection

The design as a double voice coil woofer brings with it a lot of flexibility in terms of the choice of amplifier. Whether 1 x 4 ohms, 2 x 2 ohms or 1 x 1 ohm impedance - any configuration is possible with these deep bass guarantors.
