These speakers are able to produce a wide range of sound which blows many others out of the water!
None that I can really hold against these speakers. They are small speakers so you can't expect the same performance you would get from 5 x 7's or any other larger speaker.
These are very good speakers. I installed them in my 1990 VW Golf and I am VERY impressed with the sound quality. Included in the package are a pair of low pass filters which allow you to use these speakers to their max.

Full sound reproduction and loud just off of stereo power. Marine certified for my two seater convetable.
These speakers are replacements for the four 3 1/2s in my two headrests of my two seater convertable. They are running off of just the stereo and sound great. I am suprised at how much full sound I get from them since the woofer is so small. They are a great compliment to my db 5 1/4 components.
