Active Subwoofer 70W (20cm)

AXB20A 20 cm / 8″ active subwoofer 70 W RMS

Compact, powerful and modern in design – with its gross internal volume of 8.3 liters, the chic ‘mini bass wonder’ can even be positioned in the trunk of small vehicles. The AXB20A was developed for music lovers who don’t want to do without trunk loading space or bass accompaniment on the go. Since AXTON’s compact box can not only be quickly installed but also removed, the active subwoofer is also suitable for leasing vehicles, for example, where as few changes as possible should be made.
