PROPRIETARY HEAT SINK
All Alphasonik 400 Series subwoofers have motor structures encased in pat- ent pending, 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.
MINERAL FILLED POLYMER INVERTED DOME
All Alphasonik 400 Series Subwoofers use the latest technology with mineral filled polymers for musical neutrality. The inverted dome geometry can handle tremendous stress without deformation.
EPDM SURROUND
All Alphasonik 400 Series Subwoofers employ EPDM surrounds. This high- tech synthetic rubber exhibits both high tensile strength and compliance over a wide range of temperatures.
