ATB20STP 20 cm / 8″ Active Subwoofer for the spare wheel well 90 W RMS

Bass fun without wasting valuable space in the trunk? AXTON is expanding its range with a second space-saving active subwoofer variant: The ATB20STP is a 20 cm bass reflex woofer with a built-in active module for installation in the spare wheel well. With a diameter of 50 cm and a height of 15 cm, this subbox not only fits into almost any standard spare wheel well, but also into the increasingly shallow wells – and will therefore continue to take up no space in the trunk. AXTON’s new bass maker is equipped with a powerful 20 cm (8″) long-throw woofer that guarantees powerful, dynamic sound. The very high-quality amplifier module, which is quite unusual for this price range – discretely constructed with transistors – delivers a whopping 110 watt maximum level for all-round bass enjoyment.
