{"id":9875,"count":0,"description":"As H.D. Harwood's illustrious career at the BBC Research Unit drew to a close, he discovered a new type of thin-film plastic that seemed suitable for speaker cones. With the BBC's consent, he was granted a patent, and after his formal retirement, Harbeth was founded, and Harwood began his career as a speaker manufacturer. Advertisements in high-fidelity media announced the launch of his first product in 1977, the HL Monitor (Mk1), built around his newly patented world's first polypropylene cone mid-bass speaker. Compared to the best hand-doped first-generation Bextrene plastic cones in early BBC monitors, it produced a louder sound, handled more power, was more sensitive, had tighter bass, and less coloration.","link":"https:\/\/soundglory.com\/en\/brand\/harbeth\/","name":"HARBETH","slug":"harbeth","taxonomy":"pwb-brand","parent":0,"meta":[],"_links":{"self":[{"href":"https:\/\/soundglory.com\/en\/wp-json\/wp\/v2\/pwb-brand\/9875","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/soundglory.com\/en\/wp-json\/wp\/v2\/pwb-brand"}],"about":[{"href":"https:\/\/soundglory.com\/en\/wp-json\/wp\/v2\/taxonomies\/pwb-brand"}],"wp:post_type":[{"href":"https:\/\/soundglory.com\/en\/wp-json\/wp\/v2\/product?pwb-brand=9875"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
