Astrum SM040 · 2.1-channel multimedia speakers
Bring a subwoofer and two satellite speakers together with the Astrum SM040. The manufacturer specifies 20 W RMS total audio output, Bluetooth 5.0 and a selection of wired and removable-media inputs. A front control panel and included remote give you more than one way to manage everyday listening.
Choose your source
The SM040 lists Bluetooth, AUX, USB and TF-card input options, along with built-in FM radio. Supported media formats and capacity limits are not specified. The USB listing does not establish a USB sound-card connection to a computer; check the intended playback mode before connecting your device.
A complete speaker arrangement
A 4-inch subwoofer driver is paired with two 3-inch satellite drivers. The manufacturer lists an 80 Hz–16 kHz frequency response, OCL amplification and magnetic shielding. These specifications describe the system; room placement, source material and listening level still affect the result.
Mains input is listed as 100–240 V AC at 50 Hz. The 20 W RMS figure describes audio output, not electricity consumption. Exact media formats, port functions, supplied mains-plug details and the older bass-impedance reference still require confirmation.
