Pioneer HPM-700 Speaker System (1980-1982) Review & Demo
Pioneer HPM-700 4 Way 4 Speaker Bass Reflex Speaker System (1980-1982).
The Pioneer HPM-700 is a high fidelity, 4-way, 4-speaker Bass-Reflex loudspeaker system designed by Bart Locanthi and his team of ex-JBL engineers, manufactured in Japan for the Pioneer Electronic Corporation from 1980 to 1982.
HPM stands for “High Polymer Molecular”, in reference to its then newly-developed high polymer molecular film supertweeter, a design that is used to convert electrical energy into sound to a degree that had previously only been theory. It is damped by elastic materials to prevent the deterioration of its best characteristics, and eliminates excessive harmonic distortion.
The HPM-700, were released along with the HPM-900. The HPM-700 was comparable to the HPM-60. The tweeter and mid-range drivers on the HPM-700 and HPM-900 contained individual metal grills to protect the cones. These two speakers featured another new supertweeter design – one that more closely matched the 180 degree projection of the HPM-100. The woofers were constructed with graphite modulus – a stiffer composite material, and had foam surrounds. Also like the HPM-40 the cabinet was covered with vinyl instead of veneer.
