pioneer hpm-100's are they that great? help

I looked at a pair of HPM 150's at the Goodwill the other day...

The thing I saw is how the carbon-laminate stuff the cones are made from can fail over time. They became brittle and failed, they almost fell apart when I flexed them. That is probably why the earlier poster claimed he "blew" his up.

Otherwise, I wanted to bring them home with me.

Dude,
I have never seen the HPM-150's in person just pictures and they are more space age kind of looking. Did ya give um a try ? Even blown foams can play. I think they were rated at max 400 watts so I am sure most people who had these never powered them correctly and just blow them to hell with distortion as they clipped their 100 watt receivers. You might have picked them up at about $50 bucks and just re-foamed any drivers that had failed. The top had very odd looking super tweeter if I am not mistaken. What price were they selling them for at the thrift store if I could ask? Just the low end bass drivers alone where probably running in the same pressure levels that todays modest subs perform and that was easy for those bad boys. I am pretty sure that all the larger drivers in the pair of HPM-150's you saw were different in that they had real rubber foam around the driver instead of the paper that looks tar coated like my HPM-60's. For that reason the failed foams might have been made out of entirely different materials than my pair of 60's, you see my pair of speakers have no rot at all and they are just as old "30 years now" as the pair in the thrift store you saw. Dude you should of bought them just for the parts like the crossovers and such I know that Oaktree would of loved to have had the parts to sell by piece to others owners. Thanks for letting us all know that the bargains are still out there for the DIY fixer uppers like myself.

Dude check out the rack of Pioneer Silver Face 70's stuff and look through the pictures of the HPM-150's this guy had on e-bay, very cool indeed..........back in the day my friend...........back in the day..........!!!
