MAINTENANCE! Popular 500/800/1200Hz crossover frequency variable network. Just move the jumper pin to switch the frequency. It is useful when you want to try out horns and drivers in a variety of ways. The appearance has small scratches, but it is good for ages without noticeable scratches on the whole (Shota Sasaki)
Maintenance information: 2020.8.12 Maintained (rust removal (pickling) treatment of rear terminal screws and bridge plates. Correct the orientation of the front terminal and tighten it. Switchable SW contact cleaning ATT disassembly and contact cleaning and contact grease application Frequency characteristics measurement check (~42 kHz) and continue to use the original capacitor for good results. Input and output waveform and balance check, sound output check.)
