If you are looking for a subwoofer for a small room, the Bowers & Wilkins ASW608 is for you. This active subwoofer is only 26 centimeters high and wide. Despite its compact size, the subwoofer delivers a solid bass response thanks to the 200 mm driver and the 200 watt output power. Put on a song or movie and listen to powerful bass and effects. With the Bass Extension switch you can easily set how heavy the bass sounds. You have a choice of 3 levels, ranging from a subtle to a deep bass.
