Maintained! Professional cross 800Hz network. The internal capacitor was replaced with a Dayton one. It's an exhilarating sound with a great vantage point. How about making a 2WAY horn system with a 16Ω unit? serial 28100/28523
Maintenance information: 2020.6.4 Maintenance implementation (terminal rust removal pickling treatment, cleaning, insulation bushing & mounting screw replacement, SW type ATT contact cleaning, frequency characteristic measurement check, and continued use of the original capacitor for good results ~ approx. 42 kHz, input/output waveform and balance check, sound output check)
Accessories: none
Main specifications: Crossover frequency 800 Hz impedance 12 to 16 Ω W122 × H154 × D132 mm 1.9 kg/1 unit
Maintained! A type with few exhibitions! Crossover 800Hz network. It is an indispensable gem for 2-way systems. There is a feeling of use, Kusumi, small scratches (Sasaki Shota)
