Yep, that's Harman's (JBL/Infinity/etc) address.  Back in the day (80's and 90's) all of their drivers were built in a factory in Indiana... Pyle Industries, Inc. where I was the engineering manager.  That was my grandfather's startup after he sold Utah speakers in the mid-70's.  Both Utah and later Pyle made most of the OEM speakers for the US up until about 2000, including all of the jukebox and home organ speakers, going back to at least 1947.  Also Peavey, Electro-Voice, Fender-Rhodes...
