I recently bought a pair of Pioneer HPM-100 loudspeakers whose sound quality has been praised by several friends of mine in spite of their age. I got them all set up right away and played one of my favorite vinyl records. I immediately heard a difference between both the left and right sides. I was disappointed. I realized that the unbalanced sound imaging came from the mid driver of the right speaker, which was broken. I asked for help to get the system to work correctly.
Once the mid driver had been repaired I connected the loudspeakers to a Pioneer M-90A amp and a C-90A preamp, I put a Johnny Hodges CD in the Pioneer DV-09 player and listened to "All Of Me".
The sound is fabulous with powerful lows, balanced mids and smooth highs. The imaging is precise (I can localize every musician with my eyes closed), the sound is round and I can even hear the breath of Johnny on his reed.
I was shocked because I had found again an old, nuanced, rich and exciting sound. I played the song again, turned the volume up and it gave me goose bumps!
Is it the harmonious mix of components? I put a Johnny Hodges vinyl record on my Thorens 320 MkII and it sounds even better.
I strongly recommend these loudspeakers. If you find them, don't hesitate to buy them but try to feed them with high quality components (my first test with an integrated amplifier was not so impressive). I won't give these HPM-100 the best grade to but they come really close to it!

Speakers heard in a consignment shop with power amp and preamp: the overall quality is amazing for speakers of that time ... the dynamics of frenzied rock are impressive! (Two times one hundred watts eligible sensitivity 92.5, 26.7 kilos). Quality JBL L100 close to me, besides the same time, 75-80 years.
However the limitations are noticeable on very recent recordings (mostly classical) tweeter and super tweeter integrated (three four-way HP) tend to become invasive with a high level. In summary pregnant cumbersome but a great value especially in light of current low-end productions ....

After a few weeks Coutes attentive, I am surprised by these big trs monitor speakers from the workshops Pioneer in 1977. The HMP-100 are extremely prcises in the image and sound dtails. public records are a rgal and since their purchase, many albums that I ngligeais returned to the plate more than once for the pleasure of listening environments in which I do not pay attention before prtais . Conversely, few albums have agreed to a mastering lgrement lost their appeal. The ranon an enclosure without artifice probably not a coincidence that their crateur, from JBL, a bottom branch Pioneer TAD few years later ...
The grave is not indented. 30cm of the HPM-100 bass-reflex load can reproduce without distortion frquences low impact with a jubilant. The rigid construction of these heavy speakers matrise part of this remarkable grave. In fact, the power handling is not leve the dtriment of distortion. Whether low or high volume, the HPM-100 are always intelligible and enjoyable listen. The records do not change their plan when you push the volume, while parat matris.
As in the prcis Previous report, the high is a bit put forward on some recording. Fortunately potentiomtres in faade allow direct bearing trend. Thus, an APRS rglage fast, the HPM-100 become almost neutral and transparent, a rgal.
Buy 70 the pair on a garage sale, these speakers are a bargain. Within days, they replaced the Val de Marne Davis Acoustics j'coutais yet pleased that for over ten years. This price is of course largely trs of intrinsque quality of the speakers.
Dsormais I n'hsiterai more monitors to the high end of the seventies as long they do not suffer the time, their qualities are suprieures appearances. These speakers over 30 years could remonstrate many current productions dizzying prices. The final score reflects the price well Obviously, however, APRS will cost you, I would pay more for their prt surprising quality.
A purchase that has become curiosities vritable a favorite!
