Sub
Subjectively, I owned the R100, currently own the R200 and I am looking very very hard at the R700. Comparing the R100 and 200, they both tonally sound the same but a 5 inch woofer is never going to give you the same impact of a 6. The R100 crumbles at higher volumes, starting to scream and shout, losing composure real quick. The R200 remains composed at the same volume, they almost sound like different speakers at this point. The R100 can take a lot of power, dont get me wrong but its going to sound sissified against the bigger brother. I dont really usually like smaller neutral speakers (especially 4 inchers) they sound boring as hell, and the R100 is on the edge of that line. With or without a sub, Ill deifinitely take the R200s anytime anyday, maily because of how it handles power. The R700 will most probably be my end game speakers, amplification is goin to cost my left nut though.
