    YES. The SoundExtreme meets the IPX6 waterproof standard. The SoundExtreme can be used by the pool, the hot tub and the ocean without issues. Batten down the hatches and play your tunes worry free!

    What is IPX6?

    The IPX6 Waterproof Standard means that the product is protected against strong water jets. This means that IPX6 products, including the SoundExtreme can withstand use around water.

    The SoundExtreme waterproof speaker connects to any device that uses Bluetooth connectivity for audio. Laptops, Desktops, Tablets and Smartphones are all compatible! All Apple, Android, Blackberry and Windows devices are sure to be compatible.

    How far can the SoundExtreme be away from my Bluetooth device?

    The connectivity for the SoundExtreme is designed and tested to far exceed 30m (up to 100ft) from your Bluetooth device. Walls, leaded glass windows and metal studs inside the drywall will affect the range operation.

    The sound is distorted, how can it be improved?

    Try lowering the volume control of your connected device or musical instrument. Also, try to reduce the overall volume of the SoundExtreme

    Make sure that your device is compatible with Bluetooth. Turn off your SoundExtreme and Bluetooth device, then power on and reconnect. Make sure that Bluetooth mode is selected on your SoundExtreme

    Volume level is low when playing, how do I make it louder?

    First, increase the volume on your device to maximum. Next increase the volume on the SoundExtreme by pressing the Volume + button. If increasing the volume on the SoundExtreme and / or increasing the volume on your Bluetooth device does not work, the SoundExtreme may be in Power Save Mode.

    How can I improve the audio from my soundbar?

    We make the best soundbars in Australia but did you know you can make them sound even better? Here’s how:

    • Use 3.5mm Audio cables to send audio signals to your soundbar.
    • If you’re connecting it to your TV, turn off your TV’s built-in speakers.
    • If you’re going to fit the soundbar onto an ATV or any other vehicle, fix it to the front of your vehicle, close to the steering wheel or handlebars for better sound.

    What is a good quality soundbar?

    If you’re looking for the best soundbars in Australia, there are a few features you need to look for:

    High-quality materials: Good quality soundbars are made from tough materials that can last a long time.

    Wireless connectivity: The soundbar should be able to connect to both Bluetooth and Wi-Fi.

    Ruggedness: Nothing says quality and best soundbar in Australia like a soundbar that’s mudproof, waterproof and dustproof!

    How much should you spend on a soundbar?

    Looking for good soundbar deals in Australia can be hard and some of them can be expensive. A good quality soundbar that has a great build and sound should cost a little under $600; however, prices may be higher depending on product features.

    Are soundbars with built-in subwoofers good?

    Yes, they are! With built-in subwoofers, you can have the booming sound of a subwoofer without having to connect one to your soundbar.

    This is especially great when your soundbar is designed to be used outdoors; the subwoofer can make any beach or pool party feel like a live concert—this may be one of the best soundbar deals in Australia!

    Is a soundbar better than a speaker?

    Soundbars can prove to be a better alternative to regular speakers in a few ways:

    • They already have multiple speakers built-in.
    • They can give you a surround sound experience without additional speakers.
    • They’re all-in-one devices, sporting an amplifier and other important components.
    • Their slim design makes them easy to pack.
    • They can connect with many other speakers.
    • They’re easy to fit onto a vehicle.
