Flat housing, rich bass – K 10SE. Despite its extraordinarily flat and compact design, this representative of our K subwoofer series also delivers a bass performance that can easily keep up with conventional and larger conspecifics. Thanks to its special design, this woofer is particularly predestined for hidden and space-saving installation positions, such as in the double loading floor of the vehicle. Clever down to the last detail. Extremely flat housings require sophisticated design solutions to prevent unwanted housing vibrations. In the case of the K 10SE. 2, the magnet system of the woofer is screwed to the rear wall of the housing as additional reinforcement. The rock-hard, torsion-free sandwich membrane, in conjunction with the heavy-duty double voice coil, not only converts the amplifier power into powerful sound pressure without compression, but also scores points with subtle beats. 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 – every configuration is possible with these deep bass specialists. The housing feet of the K 10SE. 2 have a double meaning. On the one hand, they are part of the construction as a downfire subwoofer and create a defined distance from the mounting surface, which is then cleverly used for reflection. At the same time, thanks to their Velcro inserts, they reliably fix the subwoofer against slipping on carpet floors, so that additional attachment is not necessary in many cases. Particularly flat 250 mm long-throw woofer with extremely torsion-resistant sandwich paper cone. Voice coil configuration selectable via connection terminal – 2 x 2 ohms, 1 x 4 ohms or 1 x 1 ohm. Downfire housing technology for perfect speaker protection and ideal bass distribution in the vehicle. Pluggable screw terminal allows quick and safe installation and removal. Extremely flat and space-saving bass reflex housing. Power RMS / Max. 300 / 600 watts. 2O x 2 / 4O x 1 / 1O x 1. Dimensions (H x W x D). Recommended “Self-Define” high-pass filter with 37Hz cut-off frequency and Q = 1.2 Additional EQ filter 95 Hz / Q = 0.7 / -3dB.
