15" | 15FIND
Ferrite Woofer
Key features:
- GLASS FIBER AND RIB REINFORCED PAPER CONE
- FEM OPTIMIZED AIR CIRCULATION
- SILICONE SEALED SURROUND
Design notes:
The 15FIND is a high efficiency, (95.5 dB 1watt / 1 meter) 15-inch woofer with incredibly linear frequency response characteristics, extreme high power handling capability while generating low harmonic distortion artifacts. The 15FIND uses a lightweight, but strong, glass fiber loaded cone assembly along with a high excursion triple roll constant geometry surround. This combination provides remarkable strength, high efficiency and a peak to peak maximum excursion of 38mm (1.5in). Power HandlingAt the core of the 15FIND is it’s voice coil technology featuring a composite Polyimide former material capable of withstanding peak temperatures in excess of 250°C, well beyond the thermal requirements of modern professional audio systems. Winding if winded on the outside and inside of the former.REDCATT has implemented a silicone spider design to ensure long term Fs memory, consistency and diminish anomalies associated with spider deterioration. The sealed spider works as a air pump and pushes the air trough out motor to increase heat transfer and cooling of the parts.
