Restoration of vintage loudspeakers Pioneer HPM-100 designed by Bart Locanthi and his team. These are 100W version. Speakers were carefully restored and upgraded. My main goal was to keep them as original as they could be. I bet they could sound even better with the mod and crossover upgrade, but it wasn’t what I was aiming for. This is my third speaker restoration. Now I have to make some defend stands for them. Something like kenrick sound stands.
– high gloss finish
– resprayed front and rear
– new midrange driver
– dust cups repaired, drivers cleaned
– deox thru
– some new internal wiring
– crossover restoration with 2% hifi caps and resistor
– new speaker binding posts
– added damping
– frames of speaker grills repaired
– high quality custom speaker cable
My local furniture guy did sanding and high gloss polish for me as it is quite struggle without tools. £90 well spent. I did black front and rear brown. Otherwise you get similar finish with yacht varnish if you are happy to do sanding and have skills to do that yourself. I used it with my previous project and actually yacht varnish is even better than this one (harder), but I thought to safe myself nerves and time.

I’ve made vintage looking speaker cables for them as well
I used to be in high end HiFi so I can compare. Honestly they are really nice vintage speakers but not so HiFi speakers in today terms. They have lovely velvety sound but lacking soundstage and resolution of today speakers. Obviously hard to compare with five figure speakers.
I love my Pioneer gear anyway and went this vintage path rather than critically waiting for every little nuances like these do called audiophiles do.
I really do enjoy music and I do it for joy of music and don’t need to spend tens of thousands to have some good fun.
This restoration was well worth it, now they sound so much better, really fantastic for vintage loudspeakers.
