18" | 186FIND
Ferrite Woofer
Key features:
  • 4.5 inch high temperature voice coil

  • High Sound pressure level

  • Very high power handling

Design notes:
    • Introducing 186FIND, the powerhouse woofer designed for superior audio performance. With a staggering 3,600 watts of peak power and a 4.5" voice coil that can withstand temperatures exceeding 350°C, this woofer is
    • built to impress. Featuring a new paper pulp mixed with glass fibers, high excursion surround, and an extra large spider, it delivers unparalleled longevity and bass. The motor system's high grade ferrite magnet creates a
    • strong symmetrical flux field, while the extended space below the voice coil allows for maximum excursion. Get ready to be blown away by the 186FIND woofer.
