I have been trying to search and find out exactly what type/size speakers come stock behind the seats in a 2007 S2k. Any ideas? Thanks!

 

I'm curious as well. I took the grills off and it looked like they were 1" but I didnt measure.

EDIT: thanks philbert post corrected.

 

the rollhoop speakers are not tweeters, they are miniture "full-range" speakers, like you'd find in those mini tower computer speaker systems. obviously they won't play bass, but do extend well into the midrange. i believe they are made by pioneer.

on modifry's site, he has sound files comparing the stock speakers with his replacement offering:

the stock speakers sound extremely thin, his replacements provide more "fullness"... i don't really want to modify my stock rollhoop covers to install the replacemnts, so i just fade my HU all the way to the front most of the time.

 

Is there a 5.5 or 6.5 inch speaker that will fit inside the roll hoop where the OEM speakers are?

 

you can get an insert that fits inside the center of the rollhoop area, which would house a 5.5 or maybe 6.5 coaxial or component set, people do that. but you would be better off upgrading the front speakers, head unit, and adding an amplifier before looking into rear speakers.

 

besides modifry replace roll hoop speakers. what else can i use or where to buy. never seen those before. $150 to do the roll hoops from modifry is come expensive since my front alpine type r speakers didnt even cost that much
