オーディオ　全てアルニコスピーカーユニット搭載のYAMAHAの NS－451のご紹介です。

This two-way speaker, released 42 years ago in 1978, uses alnico magnets for both the woofer and the tweeter. It cost ¥53,000 for two, but it's too cheap to sell at that price now. The tweeter is also made with high-quality edge-wound copper-clad aluminum ribbon. The LC network capacitors are bipolar capacitors, sold at Akizuki for ¥10 each, and should be replaced. I replaced them with Shizuki film capacitors. The sound is clear and high-quality; please listen and check it out. I played a royalty-free CD from White Co., Ltd. through the speakers and uploaded a recording using a TASCAM recorder and microphone. #audio #YAMAHA #speakers
