is the RP-450C better than the PL-28II ,ive been looking to upgrade to something with cleaner mids an treble but im wondering if ther'ers any preformence issues blending with my fronts the BIC PL-89 being that the RP-450C has four 5in drivers an the PL-28II has two 8in drivers ,i know some times that has an effect but with the RP-450C being 97dB SENSITIVITY an the PL-28II at 98dB SENSITIVITY would that make it not noticeable being different size drivers

With both speakers having a 95+ dB sensitivity rating I think you can safely discount efficiency as a factor because they're each well into the upper echelon in that regard. The question then becomes what are you looking to achieve.

Quad 5.25" drivers versus dual 8" drivers is almost a wash, as far as cone surface goes, so there's probably little to gain there. BIC are budget speakers though, while Klipsch are not, so from a quality perspective the latter will most likely sound better. However, the LCR should all be from the same family of speakers so if you replace the center you really should replace the L/R with its matching counterparts.
