speakers fo PrimaLuna Prologue One.

looking for speakers that work well with the primaluna prologue one. can be either floorstanders or bookshelves.
Try Dynaudio Audience 52 or 52 SE - both used now. These lowish sensitivity speakers seem like they would be poor match for the relatively low power ProLogue one, but they sound great together. Put the 52's on a nice stand and give them some room to breath and you will be very happy. Other options would be the Usher Be-718 (tiny Dancer) or the Focal Chorus 807V.
Look for something in the 90db. range with an 8 ohm impedance that does not drop below @ 6 ohms .

I enjoy a standmount , Reference 3a De Capo i , with my Prologue 2 .

Good luck.
I dont know if thid really help but I use Dali Helicon with my prologue seven.

ProLogue seven's are about twice as powerful as the one. With that said, the Dali's would probably sound pretty good with the ProLogue one as well. I was going to suggest the Ikon or Mentor lines.
Anything in the Klipsch Heritage series would sound great with it - I drive my Cornwalls with a Dialogue 2.
