At a garage sell this past weekend, I found some older Pioneer stuff and was wanting to know if any of you all have any info on them. The reciever is a model # SX-255R, the CD player is a PD-F807, these 2 were produced in 1998, from the tag on the back of the units..both units work perfectly, the 101 disc player has no problems at all(just needed cleaned). My big question is with the speakers all they have on them is Pioneer Quartet 70, they do have some tech specs on the back, but no other numbers other than that. The speakers look older than the other stuff, and one is missing a tweeter, other than that they sound really good. Oh, I only paid $25 bucks for all of it. So what do you all think, where can I get a new tweeter, is this stuff crap? Thanks for any info and your comments.
