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.

Description:

The RMST series of marine speakers by Rockville is our step up series that offers a 1" PEI Dome tweeter as well as more power handling! They have a larger magnet and can handle 100 watts RMS & 400 watts peak! If you are using an external amplifier we recommend this series.

These speakers are completely waterproof and protected from the elements! They are UV treated and have a special waterproof coating to prevent water damage. Also these speakers come with a 1 year warranty to give you the peace of mind you deserve when purchasing from Rockville!

Rockville engineers care about quality and sound more than anything else. The RMST65 was designed in a molded ABS plastic basket. The polypropylene cone is reliable and sounds great. This material is used on most of the top speakers on the market. We use rubber surrounds on these to eliminate unwanted distortion. In addition rubber is a very waterproof material. The 1" PEI Dome tweeter puts out incredible sounding highs. The low end bass and mids of these speakers really makes them stand out.

The RMST65 6.5" marine speakers were engineered to deliver amazing power and sound quality in the outdoors; be it saltwater, freshwater or any other harsh environments. These speakers can withstand tons of abuse and can handle 400 watts peak and 100 watts RMS each. These Rockville speakers comply with the CEA 2031 Loud Speaker Standard. This same rating standard is used by the highest end marine brands in the industry. CEA compliant means you can rest assured that the ratings are 100% legitimate. (We compared these against other brands and although some of these other brands stated higher wattage, the Rockville RMST65 speakers were able to handle more than double the power!)

Using only true marine grade components and materials, the Rockville RMST65 speakers are fully marinized against salt & fresh water conditions. They will not get damaged by fresh water, salt water, or moisture. There is also an additional waterproof and UV resistant coating to completely protect the speakers.

These speakers come with everything you need for installation including pre mounted grills and mounting hardware.
