I was in the Phillipines at that time also. It was a great time for Japanese electronics. Many fine pieces of Japanese gear was on display in the guy's rooms. Pioneer, Sansui, Kenwood, and Teac mostly.

But, it seems Japanese speaker makers had a competition going as to who could fill up the most front panel surface area with drivers. IMNSHO, they were not the best I've ever heard, but they were available and sure looked grand.
