Description:

The sound of the sea could use an upgrade.

The new JBL Marine Series Speakers are ready to take on anything Mother Nature throws your way. With Plus OneTM woofers and balanced dome tweeters, you'll hear the clarity of your audio above the raucous sounds of the sea. Designed to take on the sun, sea spray and scrub downs, these powerful speakers feature waterproof motor structures, a one-piece cast-polymer basket, a sealed magnet, and rubber surrounds.

Features:

Plus One Woofer Cones

Harman's patented Plus One polypropylene cones provide more overall speaker-cone area than other cones in its class- the result is higher sensitivity, increased low-frequency output and greater musical character.

Balanced Dome Tweeters

Weather resistant tweeters deliver a smooth high-frequency response and increased power handling for highs and mids, which equals to more lifelike sound from vocals, cymbals, brass instruments and pianos.

Designed for the Elements

Their one-piece polymer basket is designed to stand the test of time, even after long exposure to the sun and salt. Rubber surrounds offer superior edge protection and are much more reliable than foam. And a grille-mounted tweeter allows the front of the woofer cone to be sealed, protecting the motor structure from sea spray.

Individually Voiced

For most brand, 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.

OEM-Level Reliability Testing

JBL tests every speaker design to rigid specifications, subjecting them to extreme conditions that would break lesser speakers- this ideal for equipment that will be heavily driven in the elements. We freeze them, bake them, shake them, blast them with ultraviolet light and drive them at full power for days to make sure your audio investment lasts for years.

How To Install a Marine Amplifier onto Your Boat:

All About Your KRYPTON MF Series Amp:

What's in the Box:

• Amplifier
• PA microphone
• Birth sheet with tested power
• Owner's manual
• Mounting Screws
• Warranty

Description:

We took the sound of our Krypton car amps and we added top of the line marine grade parts so that they will last forever and withstand even the harshest conditions on the water.

We went a little overboard (no pun intended) to make this amp marine ready. We conformal coated the PCB board with a waterproof glue that is painted on to protect the circuitry. The heat sink, including the bottom plate, is made of aluminum which is rustproof. The end panels, internal mounting screws and hardware of the amp are made of stainless steel and are rustproof. Even after many years of use the amp will be rust free and operate like new!

The KRYPTON MF4 is a class AB 4-Channel high power amplifier with 2,400 watts peak output and 600 watts Dyno certified RMS power. The peak rating can be used to compare with brands who use peak ratings such as Boss and Power Acoustik while the Dyno Certified RMS rating can be used to compare with top brands such as Kicker, Rockford, Alpine, etc.

This amp has a very cool fully adjustable 12dB/Octave crossover. What is cool about it is that our crossover supports low pass, high pass, bandpass, and subsonic. This makes our amp ideal for subwoofers (sealed and vented), full range speakers, and midrange speakers. In high pass mode we allow you to filter out frequencies between 15Hz - 4K Hz. In full mode you will not be filtering any frequencies. The really cool part is in low pass mode you can use the high pass and low pass mode. So for example you can set the low pass mode to 50 hz, and then you can set the high pass to 15 Hz. In this case you would be playing frequencies in the range of 15-50 Hz on this channel. This would be an example of using the subsonic filter. Another option you have is for midrange speakers, you can use our low pass filter and set it really high. Lets say to 3Khz and then you can set the high pass to 150Hz and your midrange speakers will only play that frequency range. Our advanced crossover technology will allow you to really fine tune each speaker to get the sound you desire.

The KRYPTON MF4 is protected by a fully IC controlled circuit which includes mute, delay and soft start technology so that the amplifier will turn on safely every time and protect your speakers from popping.

You will also notice we decided to add a cool battery voltage display meter which looks great but also serves as a tool for you to know if your battery voltage is dropping which would affect your systems performance. We designed the amps to be able to last for many years even if you are playing them at max volume before clipping for extended periods of time.

This is a class A/B amplifier which is what we recommend to get the best sound quality out of full range speakers.

One other cool features about this amp is the marine public address system. Simply plug the microphone into the 3.5mm jack and you are ready to go. The amplifier features talk-over functionality. When the microphone is being used the music will fade to the background until you stop talking into the mic
