DS18 PRO-SM8.2 8" Professional Water Resistant Slim Midrange Speaker 2 Ohm

Motorcycle and ATV audio enthusiasts demand the highest quality for their high-end speakers because of the open-air environment that they love to be in. With hard riding comes with rigorous vibration and that can damage your speakers. DS18 wants motorsport lovers to feel confident in their speaker choice and not have to worry about moisture damage or vibration damage. To battle these problems, they have developed an amazing new set of speakers that are water resistant so if you get caught in the rain, you don’t have to worry about damage. They have also reinforced other vital parts to hold up to vibration better so you can ride hard and long in any kind of weather. The 8" Pro-SM8 helps you get the best sound possible.
