1973

I was out of the service (Navy), lived in Denver most of that year, stereo purchased on Okinawa was in storage in Iowa. Stereo was finialy set up once I entered college in 74.

1973...jr in HS...
Listening to Steely Dan and John Mayall digging on the tunes in a converted basement hangout... smoking Columbian gold bud and black Nepalese finger hash...Crazy I know.8)
Unfortunately... my bud's parakeet in room with us couldn't take the  smoke...He died happy though!!!

You killed a little bird via choking smoke inhalation. What an amusing, heartwarming story....

Wasn’t a total waste of life...you know how the munchies can get...so we cooked him up on the grill.   ; ^ )

 1973 - first year post high school, hair down to my ass, working at Columbia Records (factory), driving a 1972 Kawasaki H2 750 two cycle. Dynaco Quadaptor, 4 Martin floorstand Speakers, Thorins turntable, dynaco preamp and amp.

But me wonders if the OP was asking viability of speakers in suspended nets, I've found having speakers spiked to the floor, bolted to the stands to be the best sounding, rock solid unmovable so they don't smear the sound. Swinging around is for Tarzan not speakers.
