REDCATT 152FIND-333 - 8 Ohm

REDCATT 152FIND-333 - 8 Ohm Sub-woofer

Key Features

• EXTENDED LOW FREQUENCY RESPONSE
• Carbon fiber reinforced cone
• High excursion rubber surround

Design Notes

The 152FIND-333 is a high efficiency, (95 dB 1watt / 1 meter) 15-inch woofer with linear frequency response characteristics and high power handling capability. The 152FIND-333 uses a lightweight carbon fiber loaded cone assembly along with a high excursion rubber surround. This combination greatly improves low-frequency response and provides great level of control over the moving cone at high excursion levels. We have designed a lightweight surround, using our own rubber compound. As the result, the SPL is not compromised and the woofer can be used in professional audio applications, where high amounts of low frequencies are required. Power Handling At the core of the 152FIND-333 is it’s voice coil technology featuring a composite Polyimide former material capable of withstanding peak temperatures in excess of 280C, well beyond the thermal requirements of modern professional audio systems. The 152FIND-333 cone is extensively treated to withstand harsh environments and high humidity. Metal parts in the speaker assembly are coated for extreme weatherization protection.
