The Rhode Island AVID speaker company, that is! A post today by lico (http://www.audiokarma.org/forums/showthread.php?t=116839 ) earlier today reminded me. 1) The AVIDs were pretty good acoustic suspension speakers of their time 2) There's not too much information available on them 3) I've scrounged up a number of photos of AVIDs (mostly from eBAY) over the years. Seemed like a good opportunity to start a general info. AVID thread to me! The only distinguishing feature of the AVID family of which I am aware was the use of a minimum diffraction grille design. The grill cloth was fitted to a hardboard sheet with holes cut for the drivers. In practice, when the grilles are installed, the faces of the drivers are flush with the grille's baffle. AVID noted that their speakers were thus intended to be used grilles on. Herewith, some AVID speakers: Let's start with the BOTL AVID 60. Sorry that the "found" photographs feature an interesting surround repair on the twin-cone main drivers The grille is also featured. EDIT: I am generally at a loss to identify the original source of most of these photos :-( If you know the source, please let me/us know and I will attribute them (or remove them if I've violated any terms-of-use).
