Hi all, Yesterday I was out to the recycling centre for work, to drop off some stuff including old chargers... I take a box, dump the contents in a crate where the electronics go, come back with a second box, and inside the same crate I see a big black speaker that was not there 10 seconds before...Pioneer HPM-70 I quickly fished it out and went to ask the guy who had just put it there, do you have the second one ? And yes he did, handed it to me and said, you know, they are 40 years old.... I said yes, that's good, do they work ? Answer was yes, yes they work but they are so old ! They are sitting at work now, since I usually cycle there. So I'll have to wait till I can check them out. They are a bit beaten but not bad really. One of the woofer's dust cap is pushed in, not a big deal The exact model is HPM-70X. 10 inch woofer, 4 way. I haven't found much info on them, If any of you has them, what is your opinion ?
