Pioneer HPM-60 Speakers first generation

I picked up these first generation Pioneer HPM-60 about a month ago and finally got around to sourcing the proper surrounds of Ebay and re foaming the one woofer. The other woofer already had been done.


This pair was in better condition than the second generation HPM-60's that I had earlier.

The build quality of these speakers seems to be better with superior bracing on the inside and a cross over that uses polyester film caps than the second generation HPM-60's. The second gen used electrolytic capacitors.


I added more filling to the internals of the speakers as there was sparse material there to start.



For some reason the fake vinyl veneer seems to peel off this generation of HPM's as I have seen other images of the speakers in the same beige colour. Otherwise these speakers are in pretty mint shape and still have their spec sheets attached to the rear of the speaker.


So how do they sound?

Typical HPM rock sound with tight deep bass, very smooth lower to mid mid range and a sound that puts you in front and center in a concert, a rock concert.

These speakers were designed to to compete against the likes of JBL and Altec Lansing in the mid 70's

How do I like them compared to the second generation HPM's? Aesthetically, I think they look way better than the 2nd gen's. The sound is the same, this pair is starting to grow on me.

I have a line on PSB 50R and 70R foam surrounds that I have used in the past. I am selling them for $20.00 a pair with free shipping. they can be found on Ebay or contact me directly to buy a pair. These are for the foam surrounds only, glue and shims can be household items, like white glue and business cards cut into small strips.



The measurement are as follows

A: inside edge 6"
B: inside edge roll start 6 7/16"
C: outside roll edge 7"
D: outside foam edge 8"

Here is a picture of a woofer when done.

JBL 82 Speakers

I picked a few pairs of speakers recently a pair of Pioneer HPM-60's and a pair of JBL 82's.

The HPM-60's need a re foam job and will be featured in an upcoming post.

The JBL 82's was just a curiosity for me to listen to.




These JBL's seem to have been manufactured for the mass consumer market relying on there reputation in the bass department. The speakers did put out the typical JBL style bass from the 8 inch woofers, the tweeters were a soft dome tweeter with a titanium laminate coated on top.


So how did they sound? Deep in the bass region, sparkly highs and hollow in the mid range. These speakers were really not worth keeping in the collection and where moved along pretty quick.

These speakers appear on a regular basis in the used market and should not be over paid for.
