I purchased two of these a few months ago and now here comes the review. When I bought them there were only 2 reviews, now a bit more. I replaced some Polks that fried. I was really going to buy a set of Rockford P3’s which a guy at work recommended for about the same price as these. I spoke with another guy about the P3’s or these puppies and he said hands down get the RE SE audio’s, he swore by them. I do not consider myself a car audio expert, but not a novice either. I am very particular about the quality of the music I listen to – if it does not sound good I will not listen to it. All I can say is these speakers sound awesome! My system consist of a MTX JH600 amp, an Infinity kappa 4, Infinity kappa coax 6x9 in rear and 6.5 Infinity components in the front (all power wiring is 4 gauge). When I bought them Sonic just picked up this line so I knew nothing about them. Two of the Sonic reps out of three recommended these over RF and the one that did not listens to bluegrass – and said for rock these are the ones to get. What truly amazes me about these is their efficiency. All of the subs that I have had before these I would have to turn down the bass knob on my amp when I turned up the volume. With these once I set the bass they sound perfect at any volume. What sold me I guess was their saying “Built for Brutality” - and yes they are. My whole car shakes! Oh yeah (not mocking RF – I know they are good as well), the guy who told me to buy the P3’s came by to listen to the RE SE Audio’s and said he would buy these over the P3’s in a heartbeat! Get them if you like high end quality sound at rock bottom prices. I think Sonic could sell them for 250.0 each, I got them for 150.00 – get them before they hike up the price!
