The SUB E-12 F is the ideal low-frequency partner for a speaker combination from the ZENSOR series. It expands the frequency spectrum of your home cinema or stereo system audibly and noticeably with an extremely deep bass foundation and provides dynamic, well-controlled low-frequency reproduction. The 300 millimetre membrane of the woofer is made of pure aluminium and is therefore not only extremely rigid, but also looks very stylish. It is driven by a Class D power amplifier with 170 W sine output and an extremely linear frequency response. An integrated limiter also protects the subwoofer from overload. The heavy-duty magnet system with a massive four-layer, long-stroke voice coil ensures that the SUB E-12 F can always follow the audio signal coming from the amplifier perfectly. Volume, phase and upper cut-off frequency can be adjusted on the rear panel of the SUB E-12 F, and an automatic switch-on/switch-off function guarantees that the amplifier always switches on immediately as soon as an audio signal is present. Thanks to the bass reflex port that runs downwards, the comparatively compact subwoofer can also be placed directly in front of a wall without any problems. And since the front cover is held in place by invisible magnets, it can be easily removed to change the previously discretely elegant appearance of the subwoofer with its visible aluminium diaphragm to a technically extravagant one.
