Aktiivinen subwoofer Sonos Sub 4 musta — Class-D-vahvistin, AC 110–240 V, 40,2×15,8×38,9 cm

Sub 4 unlocks Sonos bass performance to add deep, controlled low end to your soundbar or speaker. The matte cabinet and sculptural form match Sonos products while Wi‑Fi connectivity lets you place the subwoofer where it fits best. Setup requires connecting the power cable and following prompts in the Sonos app to add the Sub 4 to your system.

Advantages

Dual force‑canceling woofers provide powerful, low‑distortion bass so low frequencies remain tight and clear even at high volume. The ported enclosure increases low‑frequency output for stronger impact, and Trueplay room tuning adapts bass to your room to avoid muddiness or harshness. By taking over the lowest frequencies from paired speakers, Sub 4 improves clarity and detail in mids and highs. Wi‑Fi connectivity and compact placement options let you stand it upright, lay it on its side, or hide it under furniture for flexible positioning.

How to use

Place Sub 4 where it best fits in the room — upright, on its side, or under furniture — and connect the power cable to a mains outlet. Open the Sonos app on your mobile device and follow the on‑screen instructions to add Sub 4 to your existing Sonos system over Wi‑Fi. After connection, pair the subwoofer with a Sonos soundbar or speaker so low frequencies are routed to the Sub 4. Run Trueplay tuning from the app if available to adapt bass to your room acoustics. To increase bass output, add a second Sub 4 and pair both with compatible Arc models.

Recommendations

For the most immersive home theater experience, pair Sub 4 with Arc Ultra or Arc. For music with wide dynamic range, pair Sub 4 with Sonos Five, Era 300, or Era 100 and run Trueplay to achieve balanced, controlled bass.
