The brand is now owned by Audiovox. Acoustic Research was well known for the AR-3 series of speaker systems, which used the 12-inch (305 mm) acoustic suspension woofer of the AR-1 with newly designed dome mid-range speaker and high-frequency drivers, which were the first of their kind. AR's line of acoustic suspension speakers were extraordinary for their time, as they were the first loudspeakers with flat response, extended bass, wide dispersion, small size, and reasonable cost. == Company history == Acoustic Research, Inc. (“AR”) was founded in 1952〔David Dritsas, "Audio's Dedicated Servant. (Henry Kloss; Kloss Video Corp.)", ''Dealerscope: The Business of CE Retailing'', Jan 2001, v43 i1 p28.〕 and incorporated on August 10, 1954 by audio pioneer, writer, inventor, researcher and audio-electronics teacher Edgar Villchur and his student, Henry Kloss. AR was established to produce the $185 model AR-1, a loudspeaker design incorporating the acoustic suspension principle based on patent US No. 2,775,309, granted to Edgar Villchur and assigned to Acoustic Research in 1956. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Acoustic Research」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
