Design Notes
The 121FIND is a high efficiency, (96 dB 1watt/ 1 meter) 12inch woofer with incredibly linear frequency response characteristics, high power handling capability while generating low harmonic distortion artifacts. 121FIND uses lightweight cone which movement is controlled by “M” shaped surround. Pistonic behavior and the long term stability
Is supported by Nomex spider. The woofer cone is treated to withstand harsh environments and high humidity.
The 121FIND was design for its best use in the 2-way applications, where excellent midrange response is required. Speaker provides good low frequency extension and delivers seizable amounts of low frequencies.
The metal parts in the speaker are coated and tested to ensure extreme weatherization protection.
