15" | 154FIND
Ferrite Mid-Woofer
Key features:
- COST EFFECTIVE DESIGN, YET WITH HIGH SPL, EXTENDED MID FREQUENCY
- GOOD POWER HANDLING
- LIGHTWEIGHT PAPER CONE, CONEX SPIDER
Design notes:
The 154FIND is a cost-effective solution for two-way and multi-way systems, together with subwoofers. It’s lightweight yet strong cone allows the magnetic circuit to be size optimized while delivering a seizable amount of sound pressure. With its high efficiency (97 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 extend mid-frequency response, making the woofer good choice for two-way and multi-way systems.Power HandlingAt the core of the 154FIND is its voice coil technology featuring a composite Polyimide former material capable of withstanding peak temperatures above 280°C. The winding with high temperature handling 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.
