I believe it was in 1979 when I visited a local hifi-shop with my brother and Dad, and they played the newly released Pink Floyd album 'The Wall' with "Another Brick In The Wall" (Part 2) on what was probably a pair of Yamaha FX-3 speakers (w/15" woofer), also newly released at that time. I was quite an exhilarating and physical experience that reverberated the whole room and our bodies.
When was the first time that you heard great sounding speakers?
For me it was 1977 at Purchase Radio in Buffalo NY. My brother and I were putting together a system that we would share at our parents house. The song was Aja by Steely Dan on a pair of Altec 19's that blew my mind at the time, I'll never forget it. They were a little out of our price range at the time. The system ended up being a Sherwood receiver, KLH speakers, a Technics SL-1950 and a cassette deck that I can't remember the make. Great memory!
