Pioneer HPM-100 Speakers (200W Version)

ABOUT

The Pioneer HPM-100 is a true icon of the late 1970s — engineered under the direction of ex-JBL designer Bart Locanthi to rival the legendary L100.

Featuring a 12″ carbon-fiber woofer, dome midrange, cone tweeter, and supertweeter, it delivers the signature “West Coast Sound” with powerful dynamics and sparkling detail.

Built like a tank with walnut veneer cabinets and precision crossover design, the HPM-100 remains one of the most collectible and best-sounding Pioneer speakers ever produced.

This pair has been fully serviced and restored, ensuring flawless performance and stunning presentation.

REFURBISHED

This pair of Pioneer HPM-100 speakers has been professionally restored and fully tested by our team to bring back the powerful, dynamic sound that made the HPM series legendary.

1. Acoustic Restoration

All original Pioneer drivers (woofer, midrange, tweeter, and super-tweeter) were carefully inspected and measured for impedance, ensuring perfect working balance across both channels.

Crossovers were cleaned, serviced, and verified for accurate frequency division, restoring the open, detailed soundstage characteristic of the HPM-100.

Internal wiring and solder joints were re-tinned and re-checked for long-term signal stability.

Level controls were cleaned and lubricated for smooth and noise-free operation.

2. Cabinet & Cosmetics

Cabinets were refinished in natural walnut veneer, polished and sealed to preserve the classic Pioneer tone and grain.

Front baffles were cleaned, and all driver mounting hardware restored.

Rear terminal panels were reconditioned for reliable connection and long-term durability.

New grille fabric was fitted to maintain the original aesthetic while improving ventilation and protection.

3. Listening & Reliability Test

Each speaker was run through a 3-hour continuous sound test with multiple amplifiers to verify tonal accuracy and stability.

Frequency response and channel matching were confirmed for balanced, lifelike playback.

Result:

A collector-grade pair of Pioneer HPM-100 speakers, fully functional and visually refined — ready to deliver the bold, articulate sound that defines the golden era of Pioneer.

SUGGESTED PAIRINGS

Matches beautifully with Pioneer SX-1050, Marantz 2270, or Sansui 9090DB receivers for a perfect 1970s full-power system.
