Great speakers . Been using these since 2013 and I must say they are brilliant. Clean clear mids and proper low frequency drivers. Long live HPM series



re: HPM-700

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.
