Super-cool LED lights

LED lights on a tower or roll bar are both cool and practical. These speakers give you practically limitless color choices, and you can enjoy steady light, a strobe effect, or programmed "light shows" – the choice is yours. You'll need MB Quart's N1-RC remote (sold separately) to control the lighting system and to sync multiple LED speakers.

Compression horn design

Compression horn designs dramatically improve speaker efficiency. And this is the fun kind of efficiency – it means it takes less amp power to produce more usable volume throughout the frequency spectrum. In other words, you can crank these speakers up and hear it all – highs, lows, and mids.

Quality components for impressive performance

The 1" titanium dome tweeter, polypropylene cone, and built-in compression horn give you smooth response and seriously impressive volume. The voice coil is made from high temperature copper and wound on a Kapton former, so it's light, powerful, and durable. This speaker is vented front and rear, so air passes through the spider and the back plate to exchange air over the voice coil. As a result, it stays cool when pushed hard. There's also a built-in crossover, so you'll hear a smooth transition between high and low frequencies – not irritating distortion.

Built tough to rock hard

These MB Quart tower speakers will perform in extreme conditions, with water-resistant components and super-strong composite baskets, magnet covers and grilles. The exterior surfaces are UV-resistant and ready to withstand broiling sunlight, while the heavy-duty (but light weight) ABS enclosure will handle hard knocks and also produce better bass. Inside, the crossover network is conformal-coated to protect against fresh and salt water spray, not to mention dust and sand. In fact, your MB Quart speakers are IPX67-rated, which means they meet the highest standards of weather resistance.

Your speaker comes with a die-cast, powder-coated mount that will resist sun, spray and dust. You'll also get a centering ring and 11 mounting hardware options that fit bars from 1-1/2" to 2-3/4".

Product Research


Marine & Powersports Tower Speaker: The NHT1 marine and powersports tower speaker is designed to sound great while playing very loud in the outdoors on your boat or off-road vehicle. The tower speaker's enclosure is sealed against the elements and features internal steel reinforcement for strength. The tower speaker features water resistant (IPX67) components; including horn-loaded titanium tweeter, polypropylene woofer, and rust-resistant internal connectors.

1" Horn-Loaded Titanium Tweeter: The NHT1 tower speaker features a 1" horn-loaded Titanium dome tweeter which delivers a very smooth musical response and high output with minimal required amplifier power. Thanks to the coincident mounted compression horn, overall volume is improved by as much as +5dB over conventional speakers.

8" Polypropylene Woofer: The NHT1 tower speaker features a UV protected, water resistant 8" composite polypropylene cone with temperature stable Butyl rubber surround mounted on a lightweight composite frame. The woofer's voice coil is high temperature copper, wound on a Kapton former which allows the voice coil to handle more power while remaining light in weight. Its high energy strontium ferrite magnet provides higher output with minimal amplifier power. This woofer design delivers deep bass & high volume while being protected from sun, sand, & water spray.

Wavelength Transparent Acoustic Lens: An integrated Wavelength Transparent Acoustic Lens improves midrange frequencies through the 8" polypropylene cone woofer.

Marine Certified Crossover: The NHT1 tower speaker utilizes a conformal coated, Butterworth 12dB per octave crossover with PTC  (Positive Thermal Coefficient) tweeter protection.

Injection Molded Enclosure & Grille: The NHT1 tower speaker is built to last with a heavy-duty ABS cast enclosure that features steel reinforcements. This ruggedly design enclosure is sealed to provided better protection from the elements and improved bass response. The speaker frame and integrated grill are also ABS UV protected which will help prevent color fade. The grille is removeable.

Speaker Wire: The NHT1 tower speaker features an attached 7" speaker wire with bare-tinned wire on the other end and comes with two butt-connectors that can be crimped onto your amplifier's speaker wire. The solid black wire is negative, while the black with white stripe wire is positive.

Mounting Options: The included mounting hardware includes practically every conceivable tower and roll-cage size option, so there  is no need to purchase extra equipment. Eleven mounting hardware options from 1.5" to 2.75" are included. The mounting hardware are Die-Cast for strength and powder coated to resisted outdoor elements of sun, spray and dust. The mounting system between the pipe mount and the tower enclosure  has an internal steel mounting plate for additional strength. The Centering ring allows the speaker to tip left/right when mounted to an arced mount which means regardless of the angle of your tower or roll-cage, the speaker is always straight. Additionally, the NHT1 tower speaker has been engineered to have less of the enclosure hanging below the mount, which means fewer friends & family bumping their heads on the speaker.

Illumination + Optional Remote: The NHT1 tower speaker features built-in variable illumination. There is 12-volt Positive (Red) and Ground (Black) lead that will need to connected. To control the tower speaker's illuminated color and "light show", you must purchase MB Quart's N1-RC remote control (049N1RC, sold separately). The N1-RC remote control communicates with the tower speaker via RF, so you don't need direct line of sight. The N1-RC remote offers the following control functions.

  • Power: Lights On or Off
  • Memory: Goes back to the last setting
  • Mode: Scroll up & down through dynamic light show modes
  • Color: Scroll up & down for solid light colors
  • Bright: Control the brightness of the LED illumination
Note: The tower speaker features a pre-programmed demo mode, if not using the optional remote.
