    Crappiest subwoofer i ever bought, dont buy unless u want a subwoofer that dont hit bass notes hardly, recommend for small system if u dont listen to music loud it distorts really bad. Bought a used double magnet kenwood subwoofer for only 30$ thats 10 times better with deep deep bass.

    You get what you pay for. This works well for low volume bass fill. Would work better as a pair or quad setup. Not very powerful for single subwoofer setup. But for$29 black friday sale not bad
