The Vintage Pioneer HPM 1500 - Unique - is one of the famous vintage speakers and the pinnacle of the HPM series. The acronym initially inconsistently meant "High Polymer Mylar", later being consistently referred to as "High Polymer Molecular", especially in the US in the 1980s. This heavy 4-way bass reflex speaker was sold from 1977 to 1980 for $500. The Pioneer HPM 150 was not a typical high-end loudspeaker, but rather a milestone in loudspeaker technology due to two changes. It introduced, on the one hand, the use of new materials (carbon fiber) for the construction of speaker cones, and on the other hand, an innovative "high-frequency high-polymer film".
Compared to the HPM 100, Pioneer's standard HPM speaker, the larger HPM 1500 is of much higher quality, with a larger woofer (15 ¾ inches) and the typical omni-directional super-tweeter found on top of every speaker.
The tweeter and midrange on the front of the speaker look (almost) identical to the HPM 100, but they are actually different parts. While the HPM 100 had to deal with distortion at higher volumes, the 1500 seems to be immune to distortion at almost any volume level.
Original housing, preserved in 100% perfect condition. None of the speakers have ever been damaged, they sound perfect. The speakers go very low, and it is noticeable even at low volume. In acoustic tracks, they can play an amazing scene. Every "jerk" in the guitar strings is felt. The vocals are very clear, where the super tweeter turns on in a particular band that is very noticeable.
I have already listened to many loudspeakers, but the HPM 1500 made an amazing impression on me, and they will not disappoint anyone. If I have to compare them to loudspeakers for PLN 20-30 thousand - I am sure that they will put not only one of them on the boards.
In addition, the set includes new bases that are new and do not differ from the color of the original wood. On-site listening.
