Performance High-performance loudspeakers represent the intersection of precision engineering and acoustic science, with neodymium iron boron (NdFeB) magnets standing as the cornerstone of modern driver design. These rare-earth magnets, first developed in the 1980s, provide the highest magnetic energy product of any commercially available permanent magnet, typically ranging from 35 to 52 MGOe (Mega-Gauss Oersteds). This exceptional strength allows for more compact, efficient driver designs without sacrificing magnetic flux density in the voice coil gap. In professional audio applications, where transient response and efficiency are paramount, NdFeB magnets enable speaker designs with sensitivity ratings exceeding 90 dB (2.83V\/1m) while maintaining total harmonic distortion below […]<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[],"class_list":["post-9090","post","type-post","status-publish","format-standard","hentry","category-blog"],"_links":{"self":[{"href":"https:\/\/www.zehsm.com\/ja\/wp-json\/wp\/v2\/posts\/9090","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.zehsm.com\/ja\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.zehsm.com\/ja\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.zehsm.com\/ja\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.zehsm.com\/ja\/wp-json\/wp\/v2\/comments?post=9090"}],"version-history":[{"count":1,"href":"https:\/\/www.zehsm.com\/ja\/wp-json\/wp\/v2\/posts\/9090\/revisions"}],"predecessor-version":[{"id":9091,"href":"https:\/\/www.zehsm.com\/ja\/wp-json\/wp\/v2\/posts\/9090\/revisions\/9091"}],"wp:attachment":[{"href":"https:\/\/www.zehsm.com\/ja\/wp-json\/wp\/v2\/media?parent=9090"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.zehsm.com\/ja\/wp-json\/wp\/v2\/categories?post=9090"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.zehsm.com\/ja\/wp-json\/wp\/v2\/tags?post=9090"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
