KEF Kube 1 active subwoofer in very good working condition, fully tested and performing as expected. The casing shows surface scratches and marks from prior use, but the unit remains structurally sound and delivers clean, deep bass. Power cable supplied.

This compact sub features an 8" active driver paired with an 8" passive radiator in a sealed enclosure, powered by a 200W Class-D amplifier. With a frequency response of 38–150Hz and RCA line-level input, it’s ideal for enhancing low-end in stereo or home cinema setups. Simple rear-panel controls allow easy integration with most systems.
