This subwoofer was there wining 6 stars out of 10 and I liked it very much.
It has a pure base sound and it is made frim a good quality materials, the pad around the center of the woofer is not going to wear out soon so, it's time for you to buy this bud guy - it will leave the best memories.
Mostly this Subwoofer is made for a medium sized car, the power (watt) is just enough to make the ground shake in within of 10m (if you put it on the ground) Make a Bass test on it and you will be satisfied.
My good suggestion: Buy it, I loved it.
This is a sabwoofer and it's made only for base. (I refer to my rating of the treble and midrenge sound)
