    THE sub to buy!!!
    Product Rating
    What is your opinion of this product?
    This sub is AMAZING. Hits harder than anything else in the class (EV, QSC, JBL, etc). The adjustable crossover feature is genius and allows you dial in more or less boom with the flick of a dial. Very durable and competitively sized so it's easy to handle for one person. Get this sub, you won't regret it!!
