It is a good starter sub if all you are looking for is some fairly good sq low end bass. it doesnt put out huge output, nor is it the top of the line sub for sq. It is a decent mix of in-between if you put it in a sealed box and give it 250-300 watts RMS. However for the cost, you could buy a much better 10 sub. Examples being: Type R, Focal, Infinity Reference, etc. Also good for small spaces as the sub is very shallow. Decent Starter sub...thats about it.
