Sub Woofer 1000 Watt QTX 18 Inch sub Woofer In tropical Flightcase. We bought 2 of these about 5 years ago as a cheap solution to a sub woofer. We were very surprised at the power of the product. The flight cases were bought second hand and re-lined to accommodate the sub woofers. We used them under 10 times, an when we bought powered speakers we found we didnt need the sub.
