Powerful Bass - For a booming audio experience

Samsung Soundbar A450 features a powerful wireless subwoofer, so whether you're watching movies or listening to music you can feel the bass.

Push the limits of your neighbours' patience with Bass Boost Mode. This sound mode delivers more power to the bass so you can feel every beat.

Select a sound mode, or let the Soundbar choose one for you. It automatically analyses the sound and helps deliver optimised, crystal clear sound.

One Remote Control - Control your Soundbar with your Samsung TV control

Control your sound bar using your Samsung TV remote, including equaliser and sound setting via the TV's Smart Hub so you only need One Remote Control for your entire home entertainment setup.

Wireless Connection with TV - Connect wirelessly, reduce clutter

Connect your Soundbar to your TV wirelessly via Bluetooth with minimal audio or video sync delay so you can reduce cable clutter, and simply enjoy intense sound.
