IMO, depending on what you paid for polks you may have gotten a good deal. They're not bad speakers. For their online sales prices their is better in that price range. However, you dont necessarily have to sell your speakers. The way your install is done will affect how well your speakers sound, meaning, sealing and deadening your door (research it). Aiming your tweeters...alot of factors. I wouldnt go through all of the time and effort of selling what you have now if its decent to you now. You'd be suprised how much better you can make the speakers you already have sound just from setting them up correctly. My suggestion to you is to simply do some reading around on this forum and others about how to correctly install and set up your speakers and go from there. Dont just go sell it all.
