JKent Posted May 20, 2015 Report Share Posted May 20, 2015 Found these at Goodwill for $13. They're from the 80s so the foam surrounds were shot. MSound provided what I needed!These little-known speakers were built in Ohio. Design Acoustics was (or became) a division of Audio Technica. Their most-recognized speaker was probably the D-12 dodecahedron shaped omnidirectional "ball". Their most highly rated was the PS-10.Specs:6-1/2 inch woofersPolymer Laminate diaphragmferrofluid cooled tweeters.12 inches by 11-1/2 inches by 8 inches.Freq Resp 55-20,000hzSensitivity 88db SPL/W/mmirrored pairImpedance 8 ohm.I now have a number of 6.5" woofer 2-way acoustic suspension speakers: These, Cizek KA-1, Bozak MB-80, NHT One.Have not done a side-by-side comparison but these little speakers have a very full sound, with bass that belies their small size.All I did was re-foam. I left the xo caps. These have that loathsome "wood-grain vinyl" but it was 99% intact and the grilles were good so I left the cosmetics alone except for a couple of chips that were filled with brown tinted epoxy. Also not a fan of the spring-clip speaker terminals but left those.Before & after shots below.-Kent Link to comment Share on other sites More sharing options...
