Continuous power handling
Voice coil diameter
Magnet material
The FW88 series is perfectly balanced for the loudspeaker systems of today. A performance-oriented range of ferrite woofers with 3.5" (88mm) voice coil and high flux ferrite magnet, incorporated into a compact but powerful motor package. The results are unexpected low frequency output and midrange extension to meet with almost any driver for two way applications.  Do more, with less, with the FW88 series.
