REDCATT 122NPW - 8 Ohm

REDCATT 122NPW - 8 Ohm Woofer

Key Features

• Carbon fiber filled paper cone
• Double silicone spider
• High power handling

Design Notes

The 122NPW is a high efficiency, (97 dB 1watt / 1 meter) 12-inch woofer with incredibly linear frequency response characteristics, extreme high power handling capability while generating low harmonic distortion artifacts. The 122NPW uses a lightweight carbon 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 22mm (0.9in). Woofer features REDCATT double silicone sealed spider. Power Handling At the core of the 122NPW is it’s voice coil technology featuring a composite Polyimide former material capable of withstanding peak temperatures in excess of 350degC, well beyond the thermal requirements of modern professional audio systems. The woofer cone is also extensively treated to withstand harsh environments and high humidity. Metal parts in the speaker assembly are coated for extreme weatherization protection.
