That is, this subwoofer, considering the price and quality of sound generated ...... but good Received well before the scheduled time I installed and tested; rendering is on top, the bass sound is very well suited the rear adjustment is fine and the Start button, you must connect it to the electrical current as well as a subwoofer output of an amplifier (this is better) I watched and listened to a film and music is a treat So for me 5 stars for the price with the quality I recommend
