Polk RTi12 bs BW 702 s2

Hey everyone. I have a pair of Polk RTi12, CSI5 center, and RTi6 surrounds.

Best Buy is having a sale on Bowers 700 s2 speakers. Wondering if I should move over to the BWs?

Question: are the BW 702 s2 towers really going to out sound my Polk RTi12?

Are the Bowers really that much better or just overpriced hype?

Thanks for your help.

I moved into house with much smaller media room only reason thinking of switching speaks as these polks are massive.

Thanks,

Jeffery
