Let Us Analyze The Features And Sound Performance of The BOSS Audio MRWT40 In Detail :

Sound Quality :

Boss is a leading manufacturer of musical instruments and audio equipment. The MRWT40 is evidence of its unbeatable craft. The system consists of a pair of 4-inch 2-way speakers made of durable weatherproof material. Each speaker has a polyurethane cone woofer and midrange dome tweeter. The woofer is 4 inches and the tweeter is 1 inch in diameter. Polyurethane is a hardy polymer. It is resilient, flexible and last longer than other building materials. It is hard like fiberglass, bouncy like rubber, squishy like mattress foam, sticky like adhesive and protective like varnish. For this reason it is fast replacing conventional raw materials like wood, metal and rubber in a number of applications across many industries. With respect to acoustic components, polyurethane makes stronger cones with greater flexibility. The result is better-sounding speakers with a longer operating life. The MRWT40 speakers have mylar tweeters. Mylar is more durable than paper as a cone material. The plastic poly compound enables the driver to process a wider variance of sound modifications and channel handling. It also protects the tweeter from ripping and tearing in case of extreme frequency fluctuations. The speakers have butyl rubber surrounds. Butyl is a synthetic rubber developed in lads. It is extensively used in speakers and sound equipment. It is chemically inert and impermeable to air. It absorbs most of the impact and abuse that outdoor speakers suffer. Butyl is also unaffected by inclement weather and keeps the internal parts of the speaker safe and dry. It ensures the sound is not affected by high winds and lashing waves. The total power of the Boss Audio MRWT40 is 400 watts and RMS power is 200 watts. It is enough for rocking booming audio for the deck of your boat, and keeping everyone onboard entertained. The frequency response of the waketower speaker system is 130 Hz to 20 kHz. It has an impendence of 4 ohm and sensitivity of 94 dB @ 1 W/1 meter. The speakers have aluminum voice coils. Aluminum is non-magnetic and does not easily combust. It is corrosion-tolerant and has a low density. It also performs well under stress in high-tension and high-compression environments. All these properties make aluminum an ideal metal for audio voice coils. It improves the overall performance of the speaker and keeps the sound quality intact.

Let us now move to the design and features of the Boss Audio MRWT40.

Design and Technology :

The Boss Audio MRWT40 is a marine waketower speaker system with a truly rugged construction. The speakers have weatherproof cabinets for keeping out rain and sea water. They are made extra-strong to stand up to the corrosive effects of sea water, wind, fog and dirt. The spiders and surrounds are also weatherproof. The outer enclosures are treated with special UV coatings for protection against harmful solar radiation. The coating also maintains material integrity and keeps the speakers looking new for longer. Please note that the MRWT40 is weatherproof not waterproof. It is resistant to splashes of water but must not be completely immersed in water. The Boss speakers have a quick fit terminal design. They can be mounted on boats, UTV roll cages, golf carts and motorcycle handlebars. The mounting clip fits bars with diameters of 1.5 to 2 inches. They are easy to install and have a simple DIY set up process. The MRWT40 requires marine speaker wires and can work with wires up to 16 gauge. The manufacturers recommend leaving some extra wire around the speakers to prevent the wire from tugging at the speakers and disconnecting due to turbulence or other extreme conditions. Each speaker needs to be connected to a head-unit output. The ideal set up would be to connect them to a separate amp with a high-pass filter set to 120 Hz. The tweeters inside the speakers have a wide-dispersion design. They disperse sound over a wide area ensuring a large sweet spot for better coverage. You can create a standard 2-channel system with 2 speakers or an expanded 4-channel system with 4 speakers (for which you will need another pair) linked back to back. For a 4-channel setting, remember to connect the front and rear to their respective left and right sides to ensure accuracy of stereo imaging. Each of the MRWT40 marine waketower speakers measures 7 inches by 7 inches by 7 inches and weighs 2.3 lbs. They are black in color and have a glossy finish. The product has a standard warranty of 1 year which can be extended by an additional 2 years taking the total warranty period to 3 years. The package includes the speakers, mounting clamps, bolts and rubber clamp adapters.
