Audio Database GOTO UNIT SD-4000/4300A/B/4500/4600 a price point -- unknown Description 　 The network by LC splitting scheme. Object for 2 ways and subset-dependency-4300 A-subset dependency-4300 B-subset dependency-4500 and subset-dependency-4600 have become 3 ways subset-dependency-4000. The air core coil which used the 1.2phi enameled wire is adopted as subset-dependency-4000, subset-dependency-4300A, subset-dependency-4500, and subset-dependency-4600. Moreover, the air core coil which used the 1.5phi enameled wire is adopted as subset-dependency-4300B. The MP capacitor is adopted as a capacitor. The barrier property is two kinds, 12dB and 6dB, and it is manufactured, measuring every set.
