2012 capacitor replaced, ATT maintained. A slightly unusual model. It is a 2-way crossover with 1200 Hz specifications. Since high frequency attenuation is up to 0/-2/-4/-6, it is possible to narrow down drivers compared to normal networks. There are small wounds and dullness (Oikawa Tetsuji)
Maintenance information: 2025.7.2 operation confirmed
2012.2.5 maintained (ATT cleaning, terminal tightening, resin seat plate crack replacement, capacitor replacement/Dayton use, input/output waveform and balance check, sound output check, frequency characteristic measurement/ ~ 42 kHz)
Accessories: none
Main specifications: 2-way network crossover 1200Hz W121 × H152.5 × D130 mm 1.3 kg
Maintained! Professional crossover 800 Hz network. It's an exhilarating sound with a good view. How about making a 2-way horn system with a 16 ohm unit? In addition to dullness and small scratches on the exterior, there is a feeling of use such as paint peeling. Serial 8091 8074 (Hiroki Aso)
