The larger of two models in the series, the ASW650 with its 12″ driver is a real bass demon. Capable of going down to 20Hz, this is a subwoofer that rocks. Bass is deep and tight and not overly boomy. Its on board 200W amp – continuous, provides serious power when needed. This unit has seen light use and was part of a living room system. Cabinets look really good and will be securely packed for safe shipping. We don’t have the original box but the manual is included.
