    Overview

    With world-renowned audio quality, JBL has sculpted their characteristic sound for almost 70 years, and that experience has culminated in their latest offering. It is all about the power, with this unit outputting up to 300W, delivering great audio performance for your music and movies. JBL Surround Sound cocoons you in delightful surround sound without having to have multiple speakers set up, not to mention freeing you from pesky wires.

    Feel each rhythmic boom within your music or TV shows, with a 10” wireless subwoofer, enveloping your entertainment area in dynamic, rhythmic bass. All this with the added bonus of having no wires cluttering up your living area.
    Dedicated Centre Speaker

    Perfect for sports commentary and dialogue-heavy films this Samsung Soundbar comes with a dedicated centre speaker for speech. This allows you to enjoy content at a reasonable volume without having to strain to hear the words.

    Surround Sound Expansion

    Instead of simply generating sound forwards, Surround Sound Expansion fires audio upwards and sideways, bouncing sound off the walls, creating an immersive surround sound experience.

    Strong Bass

    This device has been designed with a focus on its bass response. This means you’ll have full-sounding music that’s never flat or dull.

    Bluetooth Connectivity

    Wires are out, wireless is in. The simple Bluetooth connectivity in this unit makes it easy to enjoy your favourite music wirelessly.
