Pioneer HPM-200 speakers...

These are one of my all time favorites; very rare and desirable. In case you didn't know, these were designed by Bart Locanthi of JBL 375 fame and the designer of the early Pioneer/TAD drivers and systems. The HPM units on these are omnidirectional and the highs are very smooth and extended. While full range, they are more of an "east coast" speaker and well suited for reproduction of jazz, vocals and classical music. Their sealed woofers will dig deep, but are relatively inefficient. If you want to rock, consider the JBL or Pioneer 100's.
If you decide you don't want them, please let me have a shot at them!

By all means if you can pick up a pair in working condition you can always upgrade your amplification.
I've made hyperbolic statements like " my favorite JBL", best tweeter". " better than the Great Heil" etc. They sound as if they'd measure quite flat, seem very balanced and are quite musical, dynamic as all get out.
I don't detect much coloration, negligable mid bass boom, extremely enjoyable with well recorded music.

I helped a friend buy a set and then shipped them to him in Mo. I tested them with my Sansui G8700DB, 160wpc. Ozzie-"No More tears" was killer. These will play bass you would only expect from a sub. The cylinder mids and tweeters were nice and open. I was impressed and hope to find some myself when I have the cash to afford them.
I would go 200wpc or more to really get the most out of them.

It would be interesting how they would hold up to the ESS AMT3's with the Great Heil. The HPM 100's and 150's I've heard aren't in the same league. Those 200's look very interesting I must say, much different than your run of the mill HPM.
My rebilut recapped AMT3's I find are really uncolored, yet musical speaker, I was really amazed how good they sounded once I got them finished-probably why I just picked up another set!!

First of all welcome to Audiokarma and secondly pictures are widely appreciated for enjoyment and ID'ing.
One way of telling if the woofers are original or correct replacements is to measure with a multimeter. The top left driver should measure 8 ohms(or so) and the right "lower" woofer should measure 16 ohms. You can test(with the drivers in cabinet) by removing the crossover connections to the drivers.
It looks like you're good to go with the original woofers:thmbsp:

Comparing those photos with the ones in my HPM-200 file, I'd say you either have original drivers or diabolically clever copies. Congratulations. The HPM-200 is, as everyone has so far said, one of the best speakers to come out of the 1970s. As I recall, they're very inefficient. But they sound glorious.
Pioneer submitted a paper which was published by the Journal of the Audio Engineering Society (JAES) in 1975. Drawings in the article reference the tweeter array in the HPM-200.
Here's the patent, filed in 1973.
