If your looking to add that missing thumping feeling at the bottom end of your current wimpy sound system, then this is it! The Bazooka MBT1014 and the rest of the Bazooka tubes series are all made out of a strong, waterproof and great sounding poly based body. Other subwoofer enclosures are just cheap carpet wrapped particle board. Particle board on a boat has no business being on board. Just a few drops of water or moisture in the air starts what always happens sooner or later, particle board enclosures start to swell, rot, mold and eventually crumble apart taking the speaker with it. The Bazooka MBT1014 enclosure has been an easy fit in many of the tight locations found in most boats. The bass enhancement is amazing when installed properly. The Bazooka bass tube line out performs other enclosures hands down. For getting that great sounding bottom end in your boat there really is no other product like the Bazooka brand line of bass tubes.
