Description of KS-DR1004D:

Conformal Coating
A conformal coating is a protective chemical coating to safeguard electronic circuits from harsh environments that may contain moisture or chemical contaminants. It provides a barrier to airborne contaminants from the operating environment, such as salt-spray, thus preventing corrosion.

Circuit Separation Construction
Separated circuit boards of the Pre-amp and Power-amp sections contribute to a reduction in radiation noise.

Large LPF Coil
The large LPF coil provides stable, high quality sound with no distortion even when playing at high volume.

Variable HPF & LPF
Incorporates a rotary type HPF and LPF which enables fine adjustment. Compared with fixed type switching, more precise sound adjustment is possible to match your preferences.

Videos of RWB:

Includes:

• (2) Wakeboard Speakers
• (2) 360° Swivel Mounting Brackets
• Integrated Grill
• Installation Hardware

Description:

• No exaggerated power ratings: These speakers are rated with true world RMS ratings. No bootleg or exaggerated power ratings like other brands. These speakers are 150 watts RMS and 250 watts peak each. (150 watts RMS is equal to about 400 watts rated by other brands)
• Marine grade components and materials: these speakers are truly marine grade. They will not get damaged by water, salt water, or moisture. In addition the terminals (which are normally the first part of a marine speakers that gets damaged by water are made out of stainless steel and they are completely rustproof. There is also an additional waterproof coating cut completely protect the speakers.
• These can withstand all elements on the water for a lifetime of worry free use.
• The mounting screws are longer than other versions we carry to accommodate thicker mounting bars. In addition to wakeboard tower's on boats, we tested these to be perfect for installing in Jeep Cherokee vehicles and even ATV's.
• We've added a new and improved nylon mounting bracket. Nylon is strong, light weight, and can withstand the toughest conditions. The bracket features a special UV coating to protect it from the elements. A 360° rotating mechanism built into the bracket allows you to position the speaker in any direction for optimum listening enjoyment. This also gives you the ability to rotate the speaker to the front or rear of your boat for different applications.

The Rockville Difference:
Whenever you see the Rockville shield on a product you know that it has the stamp of approval. While other companies simply import products from China, Rockville manufactures the products in China to lower your cost but do so under American style supervision and quality standards to get you that USA quality that you want!

About Rockville Quality Control Procedures:
The Rockville brand stands for Quality, Innovation and Value. All Rockville products go through the most rigorous quality control standards in the industry. Products go through months of extensive testing before they reach your hands. All user functions are tested and all internal components are tested for quality. Rockville makes products that are virtually un-breakable! Rockville is one of the only brands in its class to test every concept model for weeks or months before starting production. Once production begins, Rockville sends product engineers to their factory to quality control every line of production. During production every product is tested and on top of that Rockville goes the extra mile and has their high level product engineers do an additional quality control. They test a certain percentage of all products from the production line a second time to ensure that the quality meets their vigorous standards, and to make sure that there is never a batch of products with even a slight problem. All Rockville products are backed with a hassle free warranty, though it is unlikely that you will need to use it.

Great features and great quality make Rockville a great choice.
