Dual 6.5 & Dual 8" Marine Wakeboard Tower Speaker Systems

The DWB series dual wakeboard tower speaker by Rockville is the next evolution in our ever expanding line of quality marine audio gear. You get a dual speaker each equipped with a 1˝ titanium tweeter and a 6.5˝ or 8˝ woofer. These speakers are rated with true world RMS ratings. Rockville engineers care about quality and sound more than anything else. The DWB series was designed using a molded heavy duty ABS enclosure that is practically indestructible! We’ve added a new and improved nylon mounting bracket with a 360° rotating mechanism built in. It allows you to position the speaker in any direction for optimum listening enjoyment.

We use only marine grade components and materials making these speakers truly waterproof. They will not get damaged by fresh water, salt water, or moisture. In addition, the quick connect terminals are made out of stainless steel and they are completely rustproof. These can withstand all elements on the water for a lifetime of worry free use. In addition to wakeboard towers on boats, we found that these are perfect for installing in Jeeps, ATVs, and UTVs.

 

Speaker Parts

An exploded line-art diagram illustrating the components and assembly sequence of a dual-speaker unit with a mounting clamp mechanism. Main Speaker Body: Two cylindrical speaker pods mounted side-by-side on a central bridge. Mounting Bracket Base: A flat platform centered on top of the speaker bridge featuring a central circular mounting point surrounded by four screw holes. Lower Mounting Bracket: Positioned directly above the base, this piece includes a curved clamp channel on top and a central Rotation adjustment screw passing through the middle. Upper Mounting Bracket: A matching curved clamp piece floating above the lower bracket to form a pipe or bar enclosure. Four long Mounting screws are positioned above, aligning with the four corner holes of both upper and lower bracket pieces.

 

Mounting

  1. Determine the speaker’s mounting location.
  2. Check that there is sufficient clearance in all directions so that the speaker can rotate freely without obstructions.
  3. When attaching the speaker to the wake tower, be sure to use the proper rubber fitment insert for the corresponding tube diameter. Do not over tighten mounting screws.

 

Adjustable to fit diameters from 1.75˝ to 2.05"
For bar diameters over 2.05˝, longer screws can be used.

Speaker Body: Two cylindrical speaker pods connected by a central bridge with front-facing speaker grilles. Mounting Component: A lower mounting bracket with a curved interior sits atop the central bridge between the two speakers. Indicated Feature: A black arrow points directly to a single socket-head screw (the rotation adjustment screw) located in the center of the lower mounting bracket's inner well.
