Summary: Not only do these speakers look cool, they have an awesome sound for small speakers! The treble and mid-range is customizable and the bass is clear. Not a great bass response, but better than you would get with most speakers this small. If you want more bass you need bigger speakers than a 5.25" multi-range speaker. My main complaint from my old speakers was they became very distorted at high volume.
Conclusion: JBL is an excellent choice for any speaker demands and I chose these to complement my Infinity 6x9 that I installed in the rear of my Grand Prix with a new Kenwood Headset. Excellent sound quality all round!
