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.

  1. Yeah O.K. I get you can't really get a true example of the sound quality listening back through some cheap earbuds or computer speakers, but would be nice to at least hear them work and keep in mind this fact when listening.
    But to have no sound when the moment of truth arrives is just wrong.

  2. demo no sound from the speakers at all, and you need to use vinyl and period amps and not use CD players even though they were out and even a tape deck to show the differences between the three way sound waves ?o

  3. If you are getting into Vintage Pioneer Equipment and would love to see a 7ft tall Pioneer rack that you can make follow the link.

  4. First off pioneer hpm family speakers sound excellent. As far as vintage quality you cant get much better. The sound is clean and clear and even a set of hpm 100's will hit hard on bass my dad had a set when i was growing up and he pushed them to there limits at a constant 200 watts which was there peak power. It took him about 13 years of constant use to finally blow them out he blew a woofer in one and a crossover in the other. Also to the people on here complaining about not being able to hear the speakers. Your not there in the room with them it will make no difference trying to hear the quality through your phone or computer it will only sound as good as your device or sound setup.

  5. my coment is that in 1980 was given to me the stereo receiver sx-1980 with a pair of hpm-700 and a mr.ditton 66 mkII by celestion with a turntable pl-560 brought from the U.S.of A. i bought a akai cassette deck used the gx-3 this 3 years after and at late 80´s or early 90´s a compact disc the pd-6700 and the gx-777 equalizer, this two last bought one year used by the equivalent of 500 dollars with some maintenance it´s everything working really good and one thing that i when younger was amazed were the woofers they looked that they wanted to leave the speakers and the windows from my bedroom shake as if they were gonna break i don´t know if you enjoy rock music but when i bought the new lp record at the time "1984"by van halen when listening to the "hot for teatcher" song at the begining i had to run to turn the bass down or it felt like something was going to break, before i had the es-2000 system from pioneer brought from japan(turntable,stereo receiver with the wrong fm frequencies and speakers) and with a reel to reel deck by grundig that i bought to the father of a friend of mine by 2 dollars,stay safe and keep giving advices to people with your knowledge in hi-fi.

  6. sorry but i watch the video for total nothing because there is no sound coming from the speakers, so lost my time

  7. It's limited alright: there's practically no sound to be heard from the speakers in the last part of the video. Nothing. 🙂

  8. Hello, I am looking for speakers to go with a Pioneer SX-750.

    I have a bit of a problem though. I don't know which speakers I should be looking for to do justice to the SX-750.

    The person who sold me the SX-750 said he liked how it sounds when hooked up to his Klipsch KG 1.2 speakers. He also reckons the amp. also did a good job driving a set of Cerwin Vega D-9 speakers.

    I am hoping to fill a medium-large room with a warm, natural sound and any thoughts or comments on this would be appreciated.

    Maybe I should be looking for a set of HPMs.

    Thank you. 🙂

  9. Hi, a couple of questions for you. Is the 10" woofer from the HPM 40, 60, & 700 interchangeable? Are they essentially the same? Also, what is the music in the background in your video? Thanks……

  10. Hi, I have a set of the CS922 A speakers on my YouTube page and was wondering if you could tell me what year they were made? Thank You for your Kind Response.

  11. Hi Audio,

    I like your Pioneer HPM-700 Speaker System video, would it be possible to tell me what the stands that are you are using with your HPM-100's in the background, please?
