DS18 DS-PRO-W10.4S PRO 10 Inch Water Resistant Cone Woofer 4-Ohm Svc DS18

DS18 is proud to present you with a subwoofer long awaited by all bikers alike! The DS18 PRO-W10 is a full size water resistant subwoofer made to withstand harsh elements all while not sacrificing any build quality that normally comes with marine speakers.

This hybrid both comes with a standard subwoofer basket, coil, and motor structure all while the cone of the subwoofer is water tight and made so it can take any water without risking corrosion and deformation that water naturally causes.

The magnet and basket have also been coated to withstand corrosion. The cone is made of durable light weight plastic with the rubber surround there to make sure things stay tight. This combo allows zero water to penetrate into the inner workings of the subwoofer to ensure long life and loudness.

This subwoofer is offered in single 2 ohm and 4 ohm configurations and handle 350w RMS and 700w peak power and works very well with both sealed and ported boxes.

FEATURES:

• Subwoofer made especially for motorcycles but can be used in all applications that need a water resistant solution.
• Don't sacrifice any loudness that you normally loose with IPX rated subs.
• Coated magnet and basket to help reduce the chances of corrosion.
• We have released single voice coil 4 ohm and 2 ohm versions so you can optimally set your ohm load with the amplifier of your choice.
• Durable lightweight plastic cone and rubber surround to prevent any water perturbing down into the working parts and motor of the subwoofer.
• Made to be loud and clear so you can feel and hear the thump at 70+ MPH highway speed as long as the appropriate power is supplied.
