My father was the original owner. It was always in the house but have been in storage this past year. Specs below are what I found online. I have seen some priced $1(contact info removed) reconditioned for the set. The Pioneer HPM-1100 speakers are 4-way, bass-reflex floorstanding loudspeakers featuring a 40cm Polymer Graphite (PG) woofer, a 12cm PG midrange driver, a 4.5cm PG high-frequency driver, and a double ribbon super tweeter. They have a frequency response of 25 Hz to 50,000 Hz, a sensitivity of 92.5 dB/W/m, and a max power handling of 250W, with nominal power handling of 125W. These rare 1980s speakers were designed to compete with JBL models and are known for their powerful sound and solid construction, using advanced Polymer Graphite materials for the drivers.
