I'd heard that before, but I've been unable to find any kind of authoritative documentation to that effect. In fact, no documentation at all. You are much more knowledgeable than I on these matters, 4-2-7; have you found any links or documents that attest to a contractual partnership? I'd love to delve deeper into the connection if any existed, but outside of rumor I haven't been able to find anything. Can you help?
I've discovered that despite the fact that JMTEC made components and assembled speakers that were dead ringers for Altec gear, there was apparently no cooperation between the two companies. Seems this was a case of the Japanese reverse-engineering the Altec gear for their market. (And, until some solid proof comes forward, I will continue to believe that the same happened with JBL/Sansui. What possible benefit could have accrued to JBL thru an association with Sansui? I would love to know.)
Oddly, I can't find any references to Altec taking legal action over the copies, leading me to theorize (no proof) that either 1) Altec saw no competition because JMTEC did not export their gear, or 2) Altec's patents had lapsed, or 3) Altec's finances were by that time in such poor shape that an expensive lawsuit would drive them even deeper into the red. (Again: these are my guesses. I have no proof for any of the three. Please do not repeat them as truth.)
