BOSS Audio BRT27A ATV Soundbar – Detailed Review :

Technology And Design :

The BOSS Audio BRT27A is a heavy-duty outdoor soundbar. It is designed for off-road vehicles like buggies, ATVs and UTVs. It can also be installed on golf carts, jeeps, tractors, RVs and boats. It has a rugged IPX5-rated water-resistant frame. It is impervious to low-pressure water jet sprays, and can take a splash or two. It can withstand a light drizzle, but must not be exposed to pouring rain.

The soundbar has a built-in Class D amplifier. It boosts the incoming audio signal and infuses it with enough power to drive the loudspeakers. Class D amps are more efficient than traditional Class A/B amps. They have a high-speed switching mechanism that uses less energy and produces less heat. As a result, you have a cooler in-unit temperature, and you get a more powerful audio output with noticeably deeper bass.

The BOSS Audio BRT27A has dual means of playing songs. It has Bluetooth 4.1 technology for Wireless Music Streaming. It works with Pandora, Spotify, etc, and has a Bluetooth range of 33 feet. It supports input from all iOS, Android and Windows gadget like smart phones, laptops, iPods and tablets. It has a built-in DSP processor for distortion-free sound. It also has built-in EQ for customizing your music.  

For wired connectivity, the speaker bar has a 3.5mm AUX input port. It works with the AUX outputs of MP3 players, smart phones, tablets and practically all non-Bluetooth and Bluetooth devices.

The best thing about the soundbar is that it has preamp outputs for adding extra devices. This feature allows room for customization. You can throw in additional speakers and subwoofers to expand your sound horizon as you like, which allows you to cater to a larger audience in open-air locations.

The device has a panel of multi-color LED lights. It comes in handy for illuminating the dash area after dark. You can do small tasks in its light like reading maps and finding tools in your tool kit. It works like an overhead lamp and helps you find your way around the wheel in dark conditions. The light bar has red, green and blue (RGB) lights, and can produce around 16 million different colors. The lights can be controlled with the help of a wireless remote controller. It lets you manage the speed, color, brightness and mode of illumination. You can also turn the lights off if you do not want them.

The BRT27A has a smart black powder-coated cabinet with a sturdy grille in front. Just underneath the grille in the middle of the bar is the control panel. It has buttons for play/pause, song skip, volume, Bluetooth, mute, EQ settings and LED lights. The buttons are easy to reach and operate.

The ATV soundbar has multi-angle adjustable mounting clamps. They fit bars with diameters between 1.75 to 2 inches. Setting up the system is fairly simple. Just plug it into a 12 volt power source, switch on the bar’s power and you are good to go.

Dimensions of the speaker bar are 27.1 inches (width) by 5 inches (depth) by 5.75 inches (height). It weighs 16.53 lbs.

Warranty period of the product is one year. It is extendable by another two years.

The package contains the soundbar, RGB LED remote, mounting kit, power cable, warranty card and a quick start guide.

Sound Quality :

The BOSS Audio BRT27A has great sound. It is equipped with three pairs of 3-inch full-range polypropylene speakers and one pair of 1-inch soft dome horn loaded tweeters. All the speakers are weatherproof. They pump out loud and clear music that is as realistic as can be. The amplifier adds more power. You get highly pronounced and nuanced audio with rich detail and a lot of depth. The amp touches a top power of 500 watts which is quite impressive. For an outdoor speaker, a powerful amp means more clarity and less interference. Frequency response of the soundbar is 45 Hz to 25 kHz which comfortably covers very low and very high frequencies.
