B & C 15FW88 - 15" 700W 8 Ohm Loudspeaker
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.
1400 W continuous program power capacity
88 mm (3.5 in) aluminium voice coil
49 - 3000 Hz response
98.1 dB sensitivity
Ventilated voice coil gap for reduced power compression
Double silicone spider with optimized compliance
Aluminum demodulating ring allows a very low distortion figure
