Good speakers. Well balanced and combine well with receivers SX-850 and larger. They are of the shelf type and it is very convenient to separate them 20 cm. of the floor by placing them on appropriate bases.

re: HPM-900

I wouldn't necessarily call these "Pioneer's best bookshelf speaker system". They're a bit big for book shelf speakers. These are floor standers for sure. They're great speakers and possibly Pioneer's best model. But they aren't fitting on any bookshelf.

re: HPM-900

There are a few decent pairs still out there. (I should know I own 2 pair) I'm talking about original graphite cones in all drivers, I would recommend getting the X-overs recapped, if that hasn't already been done. Then just sit back & enjoy the most wonderful musical experience that Mr. Locanthi had in mind way back in the day, amazing that these Loudspeaker's are still belting out tunes, some thirty plus years later. Oh & one more thing I believe your weight listing is a little off, they're more like 51 lbs. apiece.
