I had a set of 4 6.5" components- all Infinity. Had to replace a pair under warranty due to a blown tweeter. They didnt have the model at Circuit City, so I received store credit. I left with a 6.5" component Polk Audio pair plus some dynamat. They were not only cheaper, but in two different leagues as far as sound! Now, I have been loathing the Infinity pair that I am still stuck with in the rear for 9 years now. At least the dynamat helped them a little!
