Conclusion: These are simply hands down the best little speakers I've heard. They're unparalleled in fidelity, both treble and bass, even at very high volumes. They provide more bass, in fact, than I thought little 5-1/4's could.
Conclusion: I used these to re-place my front speakers in my Can-Am Spyder motorcycle. Since they are 2 ohm speakers they have effectively doubled the power of my head unit ( which is stock and cannot be replaced ). I can now play music quite loud if I choose to ( sometimes necessary on a MTC.
Conclusion: This is the second pair of speakers besides the GTO938 I bought and mounted in a friend's truck. Sounds really good for the price but again I don't see any reason for putting a 0dB / -3dB switch for the tweeter since you'll equalize from the source in a much finer manner.
Conclusion: I bought these speakers for the rear of my single cab ram 1500. Sound quality is pretty good, but are drownded out by front 6x9 in doors. May be a better speaker in a different location or setup.
Conclusion: These JBL speakers are a significant improvement over the stock speakers I had in my Ford Transit Connect. The sound is clearer and cleaner, musical instruments sound better, bass is much improved. The speakers do get a little screamy at very high volume, but otherwise I'm very happy.
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.
Conclusion: I am using these as a rear fill. I have them amped (80rms) and crossed over at 100hz. I originally tried 80hz, but they distorted a little bit at loud volumes. From 100hz and above, these speakers sound good. They are an excellent value.
