18" | 183FIND
Ferrite Woofer
Key features:
- OPTIMIZED FERRITE MAGNETIC STRUCTURE
- LIGHTWEIGHT, YET STRONG PAPER CONE
- HI SPL
Design notes:
183FIND is a cost-effective solution for subwoofers. Its lightweight yet strong cone allows the magnetic circuit to be size optimized while delivering a seizable amount of sound pressure. With its high efficiency (98 dB 1watt / 1 meter) and high power handling capabilities, this woofer will excel in all applications with tight budgets. The cone shape and material was developed to provide an optimum low-frequency response, making the woofer good choice for subwoofer systems.Power HandlingAt the core of the 183FIND is its voice coil technology featuring a composite Polyimide former material capable of withstanding peak temperatures above 280°C. The winding with high-temperature specification copper wire ensures the long life of the voice coil, without the costly service cycles.The cone is also extensively treated to withstand harsh environments and high humidity. Metal parts in the speaker assembly are coated for extreme weatherization protection.
