Paddle around with powerful sound

If you're into canoeing, kayaking, paddleboarding, or any other on-the-water fun, Fusion's StereoActive Bluetooth stereo will bring crystal-clear sound to all your adventures. It's designed specifically for watersports use, so if you like to take your tunes with you when enjoy a day on the water, this is the stereo to choose.

FUSION Stereoactive

The USB port is protected from rain and splashes.

Built for watersports

Some Bluetooth stereos are water-resistant, which means you can listen to them when you're lounging by the pool. That's great, but you can't take those speakers into the pool with you. Well, you can, of course, but if yours falls off the inflatable mattress and sinks to the bottom, good luck.

Not the StereoActive. It's made for life on the water, so you can take it into the pool, the Jacuzzi, or out on your kayak. The unique Puck mounting system (sold separately) lets you attach it to any vessel and enjoy your favorite digital music without worrying about waves, wakes, or splashes. And on the outside chance your StereoActive ever accidentally disconnects from the Puck (highly unlikely), it'll float. It can also survive submersion in up to 1 meter of water for a half-hour.

You can keep your smartphone safe, too, with a Fusion ActiveSafe storage container (also sold separately) which will hold your smartphone and a standard vehicle key, along with loose cards or change. You can control the audio from a compatible Garmin smartwatch using Ant.

If you like to record your activities, there's a flat mounting surface that's perfect for mounting a Garmin Virb or other action camera.

Big sound from a compact box

Speaking of audio, the StereoActive gives you plenty of it in lots of ways. The built-in AM/FM/Weather tuner keeps you up to date on current events and current conditions. An internal antenna ensures clear reception, while dedicated preset buttons on the keypad make it easy to program your favorites.

And, of course, you can also stream audio from popular music services like Pandora or Spotify using any compatible A2DP Bluetooth-enabled device. Back on land, you can plug in and play the music stored on your phone.

Designed with water in mind

Of all the smart features on the StereoActive, the directional speakers might be the one your fellow outdoors enthusiasts like the most. That's because the layout is designed to send the audio to you without disturbing everyone else on the water. The off-axis correction of the polycarbonate grille sends the sound where it ought to go with remarkable clarity. The powerful 10-watt speaker system has all the power you need to stay pumped up or chilled out when you're enjoying time on your vessel.

Get it wet with no worries

This isn't just a system that works on the water, it was made for the water. To that end, the scalloped control buttons were designed with paddles in mind. Whether you're standing on your paddle board or rowing in your canoe, you can adjust the entertainment with the tap of a paddle. The high-grade rubber key pad is plenty tough enough to take a paddling. And like it!

Built-in USB

If you store your MP3 music on a flash drive, you'll appreciate the waterproof cavity that's designed to house a low-profile USB flash drive. And if your smartphone's battery is running low, you can use the USB port as an emergency charge system, assuming the StereoActive itself has a healthy charge.

That should be most of the time, since the powerful built-in lithium ion battery will keep the music playing for up to 20 hours, depending on volume and connection type. If it does run down, you can bring the StereoActive back to full strength within three hours whether you're charging in the car or from a wall socket.

Multi-lingual voice prompts

The StereoActive features 12 unique voice prompts that give you audio feedback when you cycle music sources, save presets, and even charge the battery. And it'll even do it in English, French, German, Dutch, Italian, or Spanish, so it literally speaks your language. To change languages, just visit the Fusion website and download the language update.

Doesn't get as loud as I would have hoped and when turned up there's a crackle in the music. It does get the job done for me just wish it was a little louder and the sound was clearer.

Pros: Easy to mount/use

Love this Bluetooth speaker

Written by George, Business Process Improvement Specialist, on 5/25/2017 10:40:00 AM

I was searching for a rugged, weather resistant, good-sounding Bluetooth speaker with FM to use while working in the yard or the shed, and this filled the bill in spades. I was impressed with the sound quality, the solid FM reception, the rugged build quality, and the ease of use.

  • Pros:
  • Great sound for the size
  • AM/FM/Weather receiver built in
  • Waterproof
  • Floats!
  • Charges your phone!
  • Easy to use
  • Comes with a mount to anchor it to sport vehicles
  • Adapters for other sport mounts available

  • Cons:
  • Slightly lacking in "sizzle" on the high end. I find myself boosting the treble a few notches when listening to Bluetooth.
  • The waterproof cap that covers the connector panel is hard to remove, and it's not tethered to the speaker, so it needs to be stored somewhere safe when not in place.
  • No handle (though there is a loop for a strap or a tether).
