Upon further investigation, there is a 2-inch black ribbon around the edges which is connected to some wires on the inside -- the ribbon seems to be a kind of 'reverse pressure zone microphone (pzm)... I've tried in vain to find info on such a Cool Thing but haven't been able to find any more information.. there's http://www.remotemedia.co.uk which is a good start... any other information people have would be greatly appreciated! tag:ask.metafilter.com,2005:site.17179 Wed, 06 Apr 2005 00:39:50 -0800 audio glassmountedspeakers loudspeaker pzm speakerribbon kiwi.es
