Marantz HD 88

You guessed it: HD stand for High Definition.

Marantz, aka Superscope then, aka SRC in Japan used little tricks to achive said HD : polyester hemispherical membranes and an acoustic plug allowing to tilt the response between acoustic suspension and bass-reflex.
While the latter was a trick pioneered by Sony in 1971/72, the former -composite materials- proved to be the future for many.

I'm not sure this HD lineup to have been available worldwide. Neither am I sure of where it was built and/or designed...

Bar the boring color of the front mousse, I find this HD 88 to be quite good looking and well proportioned - anybody know if this was fair sounding as well ?
