A ribbed, UV-treated surround with white double stitching binds the suspension to a thick polypropylene cone for excellent reliability.
High-quality stamped steel is used for the basket for outstanding stability under extreme stress.
The bumped back plate allows the high-temp voice coil to move even more, so you get deeper bass without distortion.
Forced Air Cooling for excellent heat management. As the woofer's cone moves downward, hot air around the voice coil is forced out of the woofer. As the woofer's cone moves upward, cool outside air is drawn into the woofer cooling the voice coil.
The spring-loaded, satin nickel terminals accept a wide range of speaker wires, so you can get your bass up and bumping in no time!
A stiff injection-molded cone with 360-degree back bracing keeps the bass smooth and loud all day long.
