I'm currently running a pair 6.5"s and 6x9"s from the '04 model year on an MRP-F450 (70w RMS x4). I recently pulled out a Type-R 10" out of my trunk and I looking for a little more bass from my full-ranges since I'm not planning on running a sub again.

My delimma is either to get the new Type-S 6.5"/6x9"s for about $90 and underpower them about 15% or the Type-R 6.5"/6x9"s for $180 and underpower them about 30%.

I listen to alot of classic rock (Foghat, Bloodrock, Black Sabbath, etc), ska (Sublime), new rock (Three Days Grace, Hinder, etc) and some rap (insert whatever flash-in-the-pan rapper here). Not looking for same sound as my Type-R 10", I'm just really missing out on some of the lower frequencies (particularly <100Hz).

I wanted to know if anyone has run either set of speakers and what their experiences were with them and advice that they have for me.

P.S. I can also get the Infinity Kappas for dirt cheap, but I'm not real happy with the amount of volume they put out.
