With up to 4,800 W the K2 is the “smallest” amplifier in K Series. Built on the same technologies and features as present in the bigger models, it makes a full-fledged member of Powersoft’s most advanced line. Only 17.6 lbs (8 kg) light, the K2 is the ideal companion for where space, weight, and uncompromised sound quality matter. Per Step-up card a K2 can be upgraded to become a K3 – more power without replacing the entire amplifier.
