Pioneer hpm-60 (1977-1980)
4-way bookshelf speaker with carbon fiber woofer and polymer super tweeter, designed to compete with JBL's high-end models.
Overview
The Pioneer HPM-60 is a 4-way, 4-speaker bass-reflex loudspeaker system made from 1977 to 1980. It belongs to Pioneer’s HPM (High Polymer Molecular) series and was built to go up against American speakers like the JBL L100 and JBL L36. It has a 10" carbon fiber blended woofer, a 4" midrange, a 1-3/4" cone tweeter, and a high-polymer super tweeter meant to reduce narrow-beam directionality. Individual level controls for mid and high frequencies let you adjust the tone.

Design
The HPM-60 woofer is carbon fiber blended, with an ester-type urethane foam edge. The polymer film super tweeter has no magnet. It works by running current across a thin foil. First generation models have better internal bracing, polyester film capacitors in the crossover, and heavy-duty cabinets. Later versions used electrolytic capacitors and lighter enclosures. The fake vinyl veneer tends to peel, and the original internal damping material is sparse. The super tweeter has low output, and the speaker sounds bright and forward.
Context
The HPM-60 was the second model in Pioneer’s HPM series, below the HPM-100 and HPM-150. The series came about after Pioneer hired Bart Locanthi, former VP of Engineering at JBL, to take on the dominant American speakers of the 1970s. The HPM-60 aimed at models like the JBL L36 and L26. It was a compact alternative with JBL-inspired sound. It competed in a market defined by the "war for domination" among Pioneer, JBL, Altec Lansing, and Yamaha during the golden era of vintage audio.
Market
HPM-60 woofers commonly need re-foaming. DIY kits cost around $20 and professional service runs near $80. Replacement surrounds and midrange drivers (e.g., MW Audio MM-0721) are available. The speakers are sensitive to placement - they do best elevated slightly and away from walls. They are not as collectible as the HPM-100, but well-maintained pairs have listed for $450, and individual woofers appear on eBay for under $100. Some users report paying less than $200 for a pair in recent years.
