• PROPRIETARY HEAT SINK
• All Alphasonik 200, 400, 600 and 800 Series subwoofers have motor structures encased in cast aluminum machine finished heat sinks. Power handling is enhanced because excess heat is quickly absorbed and transferred to the environment. The music may get hot but our subs run cool.
