The Astrum SM020 - Proper 2.1 Sound for Your Desk. No Adapter. No Fuss.
The Astrum SM020 is a true 2.1CH desktop speaker system with a 78mm wooden down-firing subwoofer, 2 x 52mm wooden satellite speakers, 11W RMS output, and USB power directly from your PC or laptop. No external adapter. Separate bass and volume knobs. 3.5mm AUX input. Plug and play.
2.1CH - What It Actually Means
A dedicated 78mm subwoofer handles the bass, while two 52mm satellite speakers handle the mids and highs. Each driver does what it is designed for - giving you cleaner, fuller sound than a standard 2.0 speaker system at this price. Bass that feels fuller without muddying the mids.
Wooden Enclosure - Not Plastic
The subwoofer and satellite cabinets are made from wood, not plastic. Wood helps reduce unwanted resonance more effectively than plastic, which is why many quality speaker systems use wooden enclosures. It sounds better, feels better, and looks better on your desk.
USB Powered - Zero Setup
No external adapter required. Plug the USB cable into your PC or laptop, connect the 3.5mm AUX cable to your headphone output, and you are ready to go. Works with Windows, Mac, Linux, and Smart TVs with a 3.5mm audio output. No drivers. No installation.
Separate Bass + Volume Knobs
Two independent knobs on the subwoofer let you control bass and overall volume separately. Keep the bass lower for music, or turn it up for movies and gaming.
Compact by Design. Big on Bass.
With a compact subwoofer and two satellite speakers, the SM020 is designed for desktop and near-field listening. It is a significant upgrade from built-in laptop or monitor speakers, making it ideal for music, movies, YouTube, and gaming at your desk.
