The X-Tension Kit comes in two versions: one with a height of 120 cm and another with a height of 133.6 cm. The shorter model (120 cm) is inserted between the subwoofer and VENIA-6 to raise the column to a visually appealing height. The longer model (133.6 cm) serves the same purpose with VENIA-8. Connection cables can be elegantly routed through them, and the mechanics allow for quick and easy assembly using locking bolts. Both X-Tension Kit models can be mounted on any subwoofer or a steel base plate with M20 threaded mounting. For transporting the X-Tension Kit, the carrying bag or flight case for VENIA-6, as well as the carrying bag for VENIA-8, can be used.
