Marantz HD88

1 9 7 5 c.1975

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.
