AWESOME!

If you are reading this you are probably like me, highly skeptical because you are about to dish out some good pocket change, but heres the case, I currently finished my 2nd car audio system, i chose these as my components, these are awesome components, really hit the highs well, and mids are definitely strong. You will have to amp these so they can reach their full potential and you will also have to compliment them with a good pair of subs, Highly recommended product, you will not be disappointed.

Damn good sounding speaker set.

I finally got these installed in my truck. I used to install car stereo for a living and I have heard TONS of speakers. These things sound fantastic, good midrange, great clarity in the upper end. Pretty decent mid bass output (mounted in the doors). They arent a MB Quart Q series, but they have 1/4 the price of those. They are in my opinion, as good as or better sounding that the ZR JL audio series. Very nice speaker and Im happy with them. Whoever, said they are harsh needs to adjust the EQ properly. I wouldnt call them harsh, they tweeters have a tendecy to get a bit bright if you dont tone them down in the 12k range. And for the comments on power rating being low, I never have ever considered a speaker for the power rating (well highs anyways, subs are a bit different). People need to understand, distortion blows speakers, not power. If you char a voice coil, lock a speaker up from a voice coil failure or otherwise, It is because of distortion. Power didnt really have anything to do with it. If rip a spider assembly, blown the cone of the axis, or break the cone. That is because of too much power. One needs to also consider you are less likely to blow a speaker with a bit more power than its rating that with not enough power. With more power you achieve your threshold of listening level quicker and with out the distortion. Thanks again SE

One of the best

Component sets you can get. They get extremely loud and they stay crystal clear at high volumes. I haven't had any problem with distortion. Well worth the money.

Nice Package

These are nice speakers with great sound. The highs are very clear but can be almost harsh at high volumes. The crossovers will only accept 14ga. or larger wire (smaller will not stay in). Easy to install. Much better than stock or my previous Boston Acoustics 2 ways.
