Really? I have a ck3 & it has round drivers which also needs foam but it the cabinet is also specially designed for the round driver, plus room for additional tweeter (piezo). Would make no sense to install a round driver the way it looks in that pic. I’ve only ever seen the rectangular looking ones with the large flat woofer and center integrated round driver. So skippy, you seen one in person? If so, how does that work? Because on the grill, I see flat “woofer†imprinted on the mesh, but I also see 4 mounting holes for the round center speaker. How can it be flat woofer with those 4 mounting holes on the flat portion, and the round driver obviously NOT flat. And if coaxial in middle, does that make it a tri-axial speaker if the flat area is actually a speaker cone? And if it is the tall one with the ribbon supertweeter (saw an image of one of those too via google), will that make it a quadaxial? I dunno, every advertising literature I've seen only ever shows the standard looking one. I’m not quite convinced just yet, still wondering if that is a retrofit panel/driver kit someone designed specifically for the rectangular drivers, maybe in Europe or something.

Ok, I looked some more, and I think I found a video of that particular boombox with video. In it, he shows the instructions manual and the picture of the speaker on that manual looks exactly l like the CS-C7 on wikiboombox page (and also like my owners manual for the CS-C11 speakers), showing a light colored center speaker and no 4 mounting holes. That pretty much confirms to me that the drivers aren't original, at least unless I see the owners manual for that model showing the speakers like that. One more note: Looks like all the pioneers with that coaxial looking speaker thing is somewhere in Europe (Russia?). I'm inclined to believe now that they had trouble reforming the originals (which all rotted out, even new in box) so someone came up with this solution which they are probably selling over there. Just like my M70 lamp kits... if someone googles M70, there's probably enough pics of the led lit M70's to where newbies might presume they all light up like that, or are original.
