Astrum 2.1 Soundbar 80W RMS, HDMI ARC, Optical, BT 5.4, Wired Sub - SM510

80W RMS. Five Inputs. One Soundbar System.

The Astrum SM510 combines an 80W RMS soundbar system with a dedicated 5.25" wired subwoofer for clear dialogue, full midrange and deep bass that flat-screen TV speakers cannot deliver.

Why a Wired Subwoofer, Not Wireless

The 40W subwoofer connects through the dedicated SUB port rather than over Bluetooth or Wi-Fi - no pairing step and no wireless connection between the soundbar and subwoofer to maintain.

Total output is 80W RMS, consisting of 2 × 20W from the soundbar plus 40W from the subwoofer.

Five Ways to Connect

HDMI ARC provides single-cable TV audio and control, with compatible TV setups allowing your existing TV remote to control soundbar volume.

Optical provides digital audio for compatible TVs without ARC. Bluetooth 5.4 supports wireless streaming at up

to 10m with auto-reconnect. USB plays MP3 files directly from a flash drive with no separate source device required, while 3.5mm AUX provides a wired connection for compatible audio sources.

Optical and 3.5mm AUX cables are included in the box.

Remote and On-Unit Controls, Working Together

The included remote handles everyday listening controls including volume, bass, treble, EQ and track navigation from your seat. The MODE button on the soundbar provides direct input switching when the remote is unavailable.

Wall-Mountable - Hardware Included

Anchors and screws are included for wall installation and sized for the soundbar's mounting points. The SM510 can also be positioned on a shelf or entertainment unit if you prefer not to wall-mount it.
