Internal and external maintenance has been applied and brushed up. The vivid sense of dynamism and the sharpness of the high frequencies typical of YAMAHA have been revived. It has a low frequency thickness that 1000 monitors don't have. It is a timeless masterpiece with a clear sense of transparency, upper and lower driving force, and the smooth connection, and the heavy exterior with an ebony finish that stands out at a glance even today. It is in good condition due to maintenance. Serial 11478L 11478R (Yamato Yuki)
Maintenance information: 2024.4.1 operation confirmed
2023.9.4 Maintained (exterior repair/polishing/clear finish. Rear baffle repair/painting. Saran net replacement. Unit frame painting. Network maintenance (Since the terminals have already been replaced with external products, adjust the direction and tighten, apply a screw fastener, and replace the mounting screws. ATT contact status check (check that there are no gaps). A frequency characteristic measurement check (~ 42 kHz) was performed, and the original capacitor was continuously used because the results were good. Input/output waveform and balance check, sound output check) Unit detachable)
Accessories: saran net
Main specifications: 3-way sealed playback frequency band 40Hz to 20kH sound pressure level 90dB rated input 50W maximum allowable input 100W impedance 8Ω crossover frequency 500Hz/6kHz dimensions W395 x H710 x D349 mm 39 kg
The price has been reduced! 2020/11/9 sales price 70,000 yen maintenance completed. This is a 2-way network. Since bass can be pushed out well, and high frequency adjustment ranges can be obtained with 2 types of HF/MF attenuators, it is a model that is easy to match the desired sound quality. There are small scratches on the exterior due to the feeling of use. Serial 05234 07210 (Makoto Kono)
