I recently toured the Harman campus in Northridge, about two months ago. In fact, I just drove up there today to stop in at JBL Pro to pick something up. (The traffic was horrendous.)
It's true that all manufacturing has left the building as of June 30th. Mot of it went to the big Harman plant in Mexico; most of the rest was already in China.
There's still R&D going on in Northridge, but it's mostly an empty shell and very sad to see.
There were some Infinty models on display, and one model was used in the multi-listening lab in the double blind tests, revealed to us afterward, of course. I do not remember the model.
Most of the emphasis in the Infinity brand is going to automotive, which when combined with JBL, JBL Synthesis®, Mark Levinson, Lexicon, Becker, and Harman automotive brands accounts for an overwhelming proportion of Harman's total income.
As for Infinity loudspeakers for the home, I believe it's been moved to Elkhart, Indiana, to the old Crown campus along with Harman's higher end stuff, like JBL Synthesis® for the home, Revel, Mark Levinson, and Lexicon.
In that competitive environment, I think there's a probability that Infinity's home loudspeaker days are coming to a close.
