JBL Tower X Marine MT8HLB

Patent Pending Design

JBL Tower X Marine Speaker system incorporates a a patent pending angled baffle speaker design that directs the transducers to the rider's listening position instead of the water at the stern of the boat. This provides the rider with excellent sound quality, reduces the smearing effect caused by your music reflecting off the water, and provides an enjoyable listening experience for everyone else inside the boat.

Marine Rated

For JBL, failure is not an option. Extreme care was taken to engineer marine-grade materials & components that overcome the demands of the harsh marine environment. We will not rest until we are sure your product will survive for years to come.

High Output Design

At JBL, we want to deliver a concert to the water. The JBL Tower X MT8HLB includes an 8-inch long-throw polypropylene woofer cone and rubber surround, coupled with a 1-inch horn-loaded titanium compression tweeter to make sure you get the deep bass, smooth highs, superior sound quality and extreme power handling you expect.

JBL Tower X Marine Speakers feature a rugged 360-degree rotating bracket design adjustable to 1.75in. to 3in. bar sizes.

Individually Voiced

For many brands, off-the-shelf speakers and a cursory approval of frequency response curves are good enough. That’s not the case with JBL . We don’t only listen to our speakers against the competition — we voice them against each other to ensure each line has the consistent JBL sound signature that’s known and sought out by those who care about their audio. This is just part of an extensive development process undertaken by some of the best transducer engineers in the world to provide the finest listening experience at any price point.

Harman Standard Reliability Testing

JBL speakers have to undergo a testing process that would destroy lesser speakers. JBL freezes them, bakes them, shakes them, and drives them at full power for days at a time. In the case of our marine speakers, we add an intense salt spray and UV test to ensure that they provide years of enjoyment without missing a beat.
