I found this speaker to be a great value. I installed it in a ported box and put it in my pickup truck - works great. The description is misleading - but it is obvious when I researched the speaker before I bought it. It is not Powered - you need an amp, it is not a subwoofer - it only has one voice coil so it is a woofer. I am very happy with it.

Our small local group went rockin in the park all night. This speaker stood the test.
