Awesome power for their size. Amazing sound clarity.
Little bright when it comes to the overall sound. I should have got the components.
The speakers pump out some real sound. They are unbelievable for their size and for the price you pay for them, they are a steal. Getting little critical, these speakers are a little too heavy on the mids. I was expecting some crisp highs. They do have that but the vocals always will overpower the highs, no matter how much you fiddle with the head unit.

Never had a second thought that I had brought something wrong.
If only the tweeters are removable (components)
In a HK$15,000 system (about US$2000), these 4" accounts for about 4% of the cost, but they are one of the best components for an "equipment upgrade - zero vehicle frabrication" system. 1) These 4"s play and sound like larger speakers 2) These 4"s are more than willing to keep up with the 6 1/2 db6001 up front 2a) during easy listening they are warm yet they are able to take a beating at extreme loudness (without distortion) 2b) play not as loud but are not "left behind" with the same amount of power being supplied to the 6 1/2" 3) excellent mids and highs. Lows are considered good. But if we are to consider its physical 4" size, then the lows are well beyond expectation. 4) it is unfortunate that the tweeters are not removable. Otherwise, a relocation to higher level will dramatically improve the overall sounding as they are curently sitting at feet level. 5) A case in mind. These 4"s takes time to break into. Initally, they sounded like the cone is made from cardboard and the surround is made from bathroom tisue. Given enough time, these 4" started to get more mellow and is more willing to play harder at high volume.

Sounds absolutely fabulous over factory radios and you can amplify them given you the option to have them play extremely loud and clear.
There is nothing negative about these.
Polk has a great reputation for audio products. Installation was a snap on my 2000 Isuzu Rodeo. Would recommend to anyone.

Good quality, clean sound
Have not heard any problems
I have read other reviews and I guess the other customers did not have good installers to explain how they're 4 inch speakers are supposed to work! LOL. These are 4 inch speakers, they are not to have bass, thus, these are for highs and very mild mid-sound. Bigger speakers are for mid bass or you buy the higher end line of speakers, hello. Also, providing information for any speaker or system within cold weather, nothing works exactly perfect when its cold outside. example: what would happen if you stick a hot coffee mug under some cold water? It will shatter, same with speakers, you can damage them. So, start your system and let it warm up and then play at ample level til even more warm. Dont expect to get in the car and just turn the music on and expect the system to work perfect in a icy or real cold car. Common sense. These speakers are nice and clear and complete the job with great standards.
