The 6174 18" transducer is an ultra-high performance woofer designed to
reproduce low and extended low frequency material at very high SPL's. The 6174's
twin coupled magnet structures increase the power handling to 800w RMS / 1600w
PROGRAM, while the system'sconvective cooling chambers actively dissapate heat.
The 6174 offers over 2" of controlled, peak to peak cone excursion for
exceptional performance, making it an ideal choice in high performance
applications like touring class sound systems and theme park installations.
