So I've been researching speakers for a while now and have a couple questions on some sets that are pretty popular the cadence CWM-6 and Pheonix gold rsd65cs. how do these compare to say an apline type-s, polk dxi6500, or kenwood KFC-P709PS? These components I have actually been able to hear. Also how do they compare to sets in the $125-150 range like the boston s60, jl tr650csi or the kicker RS65.2 or infinity kappa perfects. I only mention the last two because I can get them for a price in the range. Any other suggestions are highly appreciated. The amp I'll be using will be either a kicker zx350.4 or zx650.4 depending on the speakers I choose.
