These speakers are ok for the size and price, but the tweeter is really harsh and overpowering. They cannot handle bass at normal driving volume, and even with the treble shut all the way off on my EQ it was still high for normal listening. The bass was less than stock speakers, but unlike stock these did not distort at all. The speakers are very clear-sounding, so I paired them up with a set of larger speakers to work like a sub and tweeter, and they work well with a crossover so my larger speaker handle low mids to bass, and these speakers handle the high mids and treble. These speakers have great response from high mids to treble, but low mids to bass are almost unnoticeable, even with -10db of cut on the high range, and there are other 5-1/2" speakers with better low-end response out there, so its not just the small size. If you need clarity and high range, these are good speakers but a little quiet, and will not even handle typical radio rock music without sounding harsh and tinny from the overly loud tweeter. I didn't even try listening to any bass-heavy music, these are clearly not meant for that.
Pros: Clarity, Crisp sound, High-mids to treble sounds great, little to no distortion. Good to pair with subs or with a crossover running the bass to different speakers. Look great!
Cons: Very minimal response in the lower half of the frequency range, Tweeter too loud, Quieter than 15 year old paper-cone stock speakers, sound tinny and harsh when used by themselves.
