I was looking for a compact subwoofer as I do not have a lot of space for a large box in the car. Based on the positive reviews I decided finally for the Pioneer TS-WX110A And how to write my predecessor already I am excited about what the small is made off. With its beautiful deep bass, it gives the plant a wonderful sound Another plus is the "remote control" with which you can adjust the frequency and the intensity. For people who do not have space for a bold box and yet do not compromise on bass Highly Recommended
