Powered Stage Subwoofers

One of my younger brothers in the Philippines is part of a rock band. He plays the guitar and sings really well. We bought him a guitar a few years ago but it was just a cheap generic type of instrument. If his band really takes off, we will probably buy him a JBL EON618S 1000 Watt Powered 18 Inch Subwoofer from Guitar Center. I think that would be a great reward for his success at performing as a musician there.
