I picked up a set of HPM-100 (50/100) from a friend that owns a storage place for $40. They are in pretty great condition. Minor scuffing on cabinets. All drivers seem to work. They have the "dope" leak found in this thread, but other than that the electronics sound good. The crossovers had some static when turned but that went away after the first few minutes. Grills in VGC. Anyway, had to brag.

Sweet. I used a pair for years, my son now has them.
I'll warn you - get ready for a barrage of people telling you how lousy they are. HPM 100s are one of the most controversial speakers ever built. Also one of the most popular on the used market. Love them or hate them. You stole them for $40, and should get a lot of pleasure out of them.
By the way, welcome aboard.

Lol, I've been in love with HPM speakers for nearly 40 years, bought my HPM 500's new in 1982 or so.
If you can hear it, they have fabulous extended upper range (the frequency response is flat up to 40 kHz or so, only down 3dB or so at 50KHz). Bass on the polymer cone woofers is amazing, but the 100 has paper with rubber suspension and will be a little different. I used to be able to hear rather far into the "inaudible" range, don't know know since I'm 64 and my ears are getting rather battered. At least when I bought them I could easily tell the difference with speakers that roll of badly above 16kHz.
Check the crossover, any eletrolytic capacitor 40 or more years old is suspect. That said, I re-capped one of my 500s and didn't bother to do the other one, absolutely no difference at all. Someday when I'm bored I will, but the speaker is in an awkward place to take down at the moment.
Placement is important with those, they can be very "boomy" if on the floor in corners. Not everyone like them though. Very much "west coast sound"
You won't need much power to drive them, very efficient. You will be deafened long before you run out of power with 80 watts per channel. I find comfortable listening level for classical to be 10% of volume control range on my KA-900, and I don't believe I ever got the volume knob past 12 o'clock on my old KA-80 40 watt amp.
