Marantz HD88
c.1975
1977
You guessed it : HD stand for High Definition.
Marantz, aka Superscope then, aka SRC in Japan used little tricks to achieve 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 1970/71 with the ULM series (SS-7600), 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 but it was nevertheless designed by Edmond May, former JBL man.
Bar the boring color of the front mousse, I find this HD88 to be quite good looking and well proportioned - anybody know if this was fair sounding as well ?
A very informative thread on AK.
A very informative thread on here as well and an Edmond May bio from the same source.
