  • Compression Horns
MB Quart, Defining Music for years, our engineering and design teams now push the envelope on audio designed for Marine and Powersports applications even further. This year, we push our NAUTIC line, typically thought of as marine products to a full blown powersports line up. Now, we can think of NAUTIC from MB Quart as the best there is for SAND & SEA.
The line of Compression Horns and Speakers feature UHS (ultra-high sensitivity) Technology. These designs are INDUSTRY FIRST Coincident Mounted Compression Horns designed to deliver inhumane amounts of SPL while distributing a full range of frequencies.

The clear advantage of these horn speakers is their ability to produce about 5dB more sound than a traditional cone speaker from a given amplifier output. That is a huge benefit on the water or the trails!

The new NAUTIC ultra-high sensitivity (UHS) speakers create a single point source with a unified magnetic structure allowing all musical energy across the frequency band to come from a single focal point within the transducer. This dramatically improves the directionality of the speaker system while the design of the compression horn improves SPL.

With minimal amplification, these MB Quart UHS technology drivers can produce 92dB from a 6.5 inch and 95dB from the 8-inch driver. By blending the benefits of a shortened horn design with our thermal formed woofer cones your music has never been this pure and it has never been this loud!
In this cut-a-way view, you can see all of the elements that make up the MB Quart NAUTIC compression horn systems. Key among these unique features is the Acoustic Lens.
Compression Horn
This unique technology allows MB Quart compression horns to produce full, rich, professional studio-monitor sound quality. The unique perforations in the compression speaker waveguide have been engineered by size and spacing of those perforations to allow midrange frequencies to pass through the waveguide while at the same time remaining firm to effectively guide the high frequency waves from the compression driver. This technology also eliminates shadowing which can occur from high SPL standard cones and creates a waveguide for emitted frequencies of the compression driver improving SPL and the sound stage.
The very compact but powerful hard ferrite magnets made of strontium carbonate make up the motor assembly which allows the diaphragm within the compression driver to develop its power.
Controlling the power of the compression horn woofer requires a very linear suspension. The compression horn woofer uses a powerful Butyl rubber surround (IIR - Isobutylene Isoprene Rubber) and spider to create a Compliance Accurate Linear Suspension. This system allows the lower frequencies to remain very musical, regardless of the volume they are pushed to achieve.
Look closely, there is some science behind this design. The enclosure is engineered to minimize the enclosures ability to add any tones, distortions or other harmonics that can cloud the sound of the music coming from the compression horn.
Look closely and you can see the aluminum mount from the wake tower or roll cage is not screwed to the composite enclosure; there is a steel reinforcing plate that allows the system to be secured to a steel mount. That allows a NAUTIC compression horn to handle the roughest rides on a boat or any other off-road or off planet vehicle. Mounting hardware for 1.5 inch pipes to 2.75 inch included.
The brilliant mounting system actually reduces the height that the enclosure will hang down from the pipe. Nearly a full inch is saved with this reduced height mounting configuration. Now, you can install an 8 inch speaker pod where before only a 6.5 inch might have fit. Bigger is always better.
MB Quart compression horns and speakers use a unique illumination with a 256 color RGB system. You can select multiple colors and shows at the same time, or using the N1-RC remote, sync all the illumination together.
Many of the MB Quart NAUTIC compression horn towers, compression horn speakers, and tower and boat speakers are available in three different finishes.

Our original Dove Grey, matte black part numbers with “B” and classic marine white (part numbers with “W”) also, watch for illumination in the part numbers with the “L”.
Many of the MB Quart NAUTIC compression horn towers, compression horn speakers, and tower and boat speakers are available in three different finishes.

For the illuminated models “L” there are limitless color choices. Optional N1-RC required for control of lighting systems and to sync multiple illuminated speakers.
8- Centering Ring
The unique MB Quart enclosure has a hidden centering ring for adjusting the horizon of your speaker grill. This feature allows the compression horns speaker component to roll left or right or 180 degrees when mounted on an angle. Simply remove the 4 screws with a hand tool; gently remove the speaker, being cautious of the waterproof seal and the cables. Then turn your grill until your logos are level, then re-mount the speaker – that is all. Here's a video that shows how to do it.
Compression Horn
For those more difficult installations, you may need to get the optional swivel mount. This mount allows your speaker enclosure to rotate up or down 180 degrees. With our Transverse Mounting design, each speaker can rotate in opposite directions. The swivel mounts are available in black, grey and white.
