Decent for price

Power Acoustik 4" speakers.
First off, these are inexpensive speakers, which is what I needed for my application. I did not get them to rattle the windows or impress an audiophile.
I did get them to replace the factory spkrs that had gone bad. I used them in the rear pillars of my Astro van.
I have really nice component speakers up front & a good sub under the center seat.
These spkrs do a good job of just adding sound to the rear area to help fill in.
For the price, sound quality and wattage they do a pretty darn good job.
Again, these arn't high end, nor do they produce high end sound, but they do sound good for the given application.
They're not too bright or tinny and obviously sound better when pushed with an amp. I feel they are a good value for certain applications, but if you were needing more precise sound reproduction and higher build quality you would probably want to invest more $$
Overall, good little speakers for the money.
