I think this is kind of like the spring reverb a friend of mine had in his 1957 Chevy (6 cylinder, 4 door , 3 on the tree). Had an AM radio since FM was not yet a thing in our area. No 8 track or Cassette either, not invented yet.

That was our version of High end audio.

Just meant that for a tweak, if you have rear speakers, You should try a spring reverb. It would give you a nice "boing-boing" echo. Kind of like yelling into a well.

Toung in cheek. No offence intended.
