Want the best sound quality possible from a soundbar system? You'll need a subwoofer to truly make the most of your soundbar. The reason being, most soundbars are inadequate at reproducing normal low, and subsonic frequencies. Without the subwoofer, there is a big gap in the audio spectrum not being filled, which can make the overall presentation sound 'thin' or 'tinny'. With a subwoofer, you will hear a full range presentation for your favourite films and television. We also stock option for soundbars with wireless subwoofers as combos, and have some of the best soundbar and subwoofer deals in Australia.
