    Product Description

    The KS118 Is a versatile, high output active subwoofer with excellent low frequencies that is suitable for live music venues, clubs, and DJ’s. A durable construction and in-built handles make it simple to transport, while an M20 threaded pole means you can position it vertically along with full-range loudspeakers.
