Our take on the Bazooka MBT8014

by Ken Nail
Bazooka

Enclosed Subwoofers 101

An enclosed subwoofer is a box with a subwoofer already installed. The advantage to buying an enclosed sub is that the manufacturer made the sub, then designed and built the box as a perfect match, so you'll get the best possible performance. Every enclosed sub has a maximum RMS power handling rating, so pair it with an amp with a similar RMS power rating to get the best performance.

A bass cannon

Bass makes up about 30% of your music, and it gives music its power and impact. A good subwoofer can make an average marine audio system sound good, and a good marine audio system sound great. Good bass is all about moving air, and a cylindrical tube translates the motion of its woofer into maximum air pressure so you hear and feel more bass. Bazooka designed the Bass Tube to act like a bass cannon, firing low frequencies throughout your vessel.

Bass Tube efficiency

MBT8014 8" Marine Bass Tubes® enclosure

The MBT8014 Bass Tubes enclosure features a waterproof 8" polypropylene woofer with a twin-layer compressed foam surround for smooth excursion. The sub handles up to 150 watts RMS for plenty of punch, and it's UV- and moisture-resistant, so you can enjoy great-sounding bass out on the water for years to come. Its 4-ohm impedance allows you to power multiple tubes with a single amp. Bazooka's patented tube design ensures accurate and efficient output, so you don't need a big amp to get big sound.

Bass Tubes enclosures fit just about anywhere

The tube's speaker and port are right next to each other, so you can get amazing results by "corner loading" your Bazooka — placing it in a corner so your boat's boundaries act as a natural amplifier, boosting bass production. Want to know more? Take Bazooka's Bass Tubes Tour.

Features

Marine Grade Construction: The MBT8014 tube features an 8" waterproof woofer. The enclosure is certified salt fog and UV resistant for 5 years and the included mounting hardware is stainless steel.

Power Rating: The passive 4 ohm 8" woofer is rated at 6 to 150 watts with a frequency response of 39-1500 Hz.

Moisture Resistant Enclosure: The enclosure is moisture, UV, and salt fog resistant for reliable operation in all conditions.

5-Way Platinum-Colored Binding Posts: The input terminals are platinum-colored to resist corrosion. The binding posts will accept bare wire, spade lugs, banana plugs, dual banana plugs and pin connectors. The posts are recessed into a cup at the end of the tube opposite the woofer.

Installation

Mounting Method: There are 2 mounting bases that are made to be attached to your vehicle or boat with the provided 1" stainless steel self-tapping screws. Once the mounting bases are installed, the tube can be placed on the bases and secured with the included mounting straps. For best results, the tube should be mounted facing into a corner, and there should be 2 to 4 inches between the woofer and the corner into which it is pointing.

packs a real punch

Written By JG, Ohio on Saturday, September 18, 2010
 
just installed in my ski boat and it sounds awesome. just a bit too large to
fit under the back seat bench, so I installed on the drivers side by my feet
under the dash and still have plenty of leg room. great sound. no complaints

Excellent

Written By bill, Annapolis, MD on Tuesday, July 17, 2007
 
I put one of these under the rear seating on my boat. The sounds quality is excellent. When cruising across the water you need lots of clean volume to hear the music. This tube delivers no problem. I’m constantly getting complements on the over all system. The Bazooka bass tube gives me performance that many larger sub boxes can’t compare too, yet it takes up a fraction of the space. I could not be happier with the sound. (and I’m a real sound snob). I also have 2 of the non-marine versions in a couple of cars

1 question already asked

Does this sub need to be supplied with power from the boat battery and also be grounded OR does it just get connected to an amp like a speaker? [ Mwatts  Sep 03, 2014 ]
1 answer
  • Two speaker leads a black and a white. powered by amp. Red lead to rear left pos, black lead to rear right neg. Supplied instructions are pretty clear. Pretty happy with sub so far, adds fullness to system and makes speakers work better in my view. be sure to move appropriate switches on your amp to bypass frequencies to speakers. Crutchfield tech support was very helpful. [ STEPHEN D   Sep 03, 2014 ]
