Hi, I have searched a great deal for information on the 15" Stephens Trusonic speaker I recently acquired with no results other than a link to Worthpoint which gives info from a previous Ebay auction. I have looked through several Stephens vintage brochures again with no results. Hoping to find some info here. I have 1 in a homemade cabinet that is actually nicely built. I have played this speaker on my Fisher x-101-st and it sounds very nice. Any info on this would be greatly appreciated. The above info that I found says it was Stephens answer to the Jensen g-610.
