Kef - KUBE-1 Subwoofer speaker set

KEF Kube-1 active subwoofer, in excellent condition. A compact yet extremely powerful subwoofer from the renowned British manufacturer KEF, known for its tight, controlled bass response and premium finish in high-gloss black.
The Kube-1 combines an efficient 150 Watt built-in Class D amplifier with a 200 mm (8 inch) active long-throw woofer and an equally sized passive ABR (Auxiliary Bass Radiator). This sealed configuration with passive radiator delivers surprisingly deep, tight and dynamic bass without annoying port noise, making it suitable for both film explosions and musical timing in a stereo setup.
Thanks to the adjustable crossover frequency, phase control and the choice between line- and speaker-level inputs, the subwoofer can be seamlessly integrated into any existing home cinema or hi-fi system.
The unit is technically and visually in excellent condition and is ready for many years of listening pleasure.
