Best audio time b4 even hearing of the sweet spot?

So many audio memories. Decades ago, before even learning of the so called 'sweet spot', we've all got a story to tell regarding experiences surrounding audio.

Mine would have to be the days of old pushin' some serious air through 4 Pioneer speakers via the latest Quadrophonic receiver Sansui had for sale. Yes juniors, before there was multichannel SACD, or even CD, we got down to the sound with the best of them.

Agana Guam, courtesy of the US of N we're pullin' 6 months barracks livin' while our ship undergoes dry dock restoration. 4 bunks to a cubicle and many times 2 sound systems per cubicle. You name it, Pioneer, Sansui, we had it...mated to the latest Panasonic auto changer. Kegs all around w/ 70's sound. Those were the days.
