The perfect formula for outstanding protection. Yamaha’s trilaminar construction consists of a polyester surface lining with a PVC-coated backside. Below this you’ll find a thick protective inner cushion. This gives you plenty of padding to keep your subwoofer safe from accidental knocks and bangs – a life-saver for any situation. Whether you’re performing outdoors, keeping your sub in storage, or transporting equipment on the road, Yamaha’s Function Speaker Cover is the perfect solution for keeping your DXS15 MKII safe.
