15" | 15FHW
Ferrite Sub-Woofer
Key features:
- HI SENSITIVITY, LOW RESONANT FREQUENCY
- NOMEX SPIDER
- STRONG, YET LIGHTWEIGHT CONE
Design notes:
The 15FHW is an ultra low frequency sub-woofer, designed to deliver large amounts of very low frequencies. With 90 dB 1watt / 1 meter sensitivity, you find this 15-inch sub-woofer with incredibly linear frequency response characteristics ideally assembled in sub-woofers for hi-fi, gaming, studios or cinema. The 15FHW uses a strong paper cone, along with a high excursion single roll rubber surround. Rubber surround material was specifically developed for this application. The shape of the surround roll was FEM optimized to ensure low distortion in whole working range. Power HandlingAt the core of the 15FHW is it’s voice coil technology featuring a composite Polyimide former material capable of withstanding peak temperatures in excess of 200°C, well beyond the thermal requirements of modern professional audio systems. REDCATT has implemented a Nomex(r) spider design to ensure long term Fs memory, consistency and diminish anomalies associated with spider deterioration.
