In my day the holy grail of Pioneer speakers was the HPM-100 model which, I think, was the largest? Frankly speaking you really don't see much of the "vintage" Pioneer/Sansui/Marantz receiver gear here, but eBay seems to have a large audience for that. Best of luck!
Pioneer HPM-40 Vintage Speakers
Hi, again. Newbie here, so please forgive my naivete. I see an abundance of listings on ebay for quite the nice asking prices. I wish to sell these locally. Can't find any listings on Craigslist, again, so wondering if people are not wanting to sell on Craigslist. If these were your speakers, and they work, what would you sell them for? Thanks so much!
