There were 3 versions of these ribbons. The original design utilized a pure silk ribbon and are significantly better than both the later mylar ribbons and the polypropelene version [last version]The earliest ratshack speakers used a mylar ribbon,the rca examples employed the poly ribbons. With a little mod work they can sound very good but should be crossed where they would operate as a super tweeter only. One of the best tweeters ever? Not even close to the purity of the Ionovac or Dukane plasma [never heard the present Acapellas].
One of the best tweeters ever, whatever happened?
I own a pair of the amazing Optimus 5 (yeah, that's right, RADIO SHACK) speakers with the Lineaum tweeter.
I modified them according to an old article by Dick Olsher, and am still amazed by the clean, fast, transparent high frequency reproduction they accomplish.
Anyone know whatever happened to Lineaum? Seems like a killer "reference" speaker could have been made using this amazing tweeter...
BTW -- I currently own a pair of M.L. Prodigys, so I have a good reference point for high frequency reproduction ;>)
