Pete B Posted December 5, 2019 Report Share Posted December 5, 2019 I always have trouble finding this historic article covering the design behind the AR-1 woofer that started it all. I thought that there was a .pdf but have been unable to find it, here's a link to it in the library here on CSP: http://www.classicspeakerpages.net/library/acoustic_research/special_sections/additional_ar_documents/commercial_acoustic_suspens/commercial_acoustic_suspens.html A few more links with background: Some history at the AES: http://www.aes.org/aeshc/docs/record.../villchur.html Ed Villchur's patent covering his new invention, filed March 15, 1954: http://www.google.com/patents/US2775309 And another link here at CSP on a very fine AR-1 sample: http://www.classicspeakerpages.net/IP.Board/index.php?/topic/8511-historic-ar-1/page/2/ Quote Link to comment Share on other sites More sharing options...
johnfalc Posted December 6, 2019 Report Share Posted December 6, 2019 Here's a LINK to Audio Magazine, July, 1955 which on page 18 has an easier-to-read version of the first article Pete B posted above. BTW ... the RADIO HISTORY site is a joy to me, audio nostalgia extraordinaire! The site itself looks like something I might have created (style-wise) 20+ years ago ... probably usable with Mosaic! Here's a link to its home page: https://americanradiohistory.com/ Oh, and just a warning, if you haven't been to that site before you might want to grab a glass of wine and plan on hours of fun time reading.
