Powerful Audio Output

The BOSS Audio MRWT69 boasts of an excellent audio output, especially when compared to other speakers in its price range. This fantastic output is facilitated by several aspects, including the 6 inches by the 9-inch woofer. The speaker houses an 80 oz magnet structure that produces a strong standing magnetic field, which works in juncture with the 1.5-inch aluminum voice coil.
Furthermore, there is a dual 1-inch advanced technology mylar dome tweeter, which allows for greater sound modification and channel handling. This, in turn, produces clear highs with little distortion. The speaker system also comes with 550W optimum power handling, 95 dB sensitivity, 4 ohms of impedance and 40Hz-20 kHz of frequency range.
Excellent Interior Speaker Construction

The speaker drivers of the MRWT69 are composed of top grade materials that are not susceptible to the elements. To begin with, we have low density, high-temperature aluminum voice coils, which are corrosion resistant as well as difficult to ignite.
Additionally, the magnet structure and voice coil are separated by magnetic ferrofluid, which conducts heat away from the coil in an effort to prevent the coil from damage even when the speaker is taking in a great amount of power.
Though the speaker is not waterproof, some of its parts like the surround and spider are completely marinized. The surrounds contain weather resistant butyl rubber, while the other components are coated with a special substance that protects them from the corrosion that comes about from exposure to salty and humid conditions.
Metallic Injection Cone Materials

The cone of the MRWT69 is made up of Polyurethane, which is a durable, flexible and resilient polymer. The unparalleled flexibility that is associated with this speaker ensures that you will enjoy great sound for a long time. Additionally, the resilient cone does not come apart when met by successive and recurrent frequency changes.
