Sonos Sub 4 Wireless Subwoofer: The Consensus

Introduction

The Sonos Sub 4 wireless subwoofer is widely celebrated by owners for its ability to dramatically enhance home audio systems, particularly when paired with Sonos soundbars. Achieving an ORA Consensus Score of 7.7/10, this subwoofer stands out for its immersive sound, elegant design, and user-friendly setup. Many describe it as a transformative addition, delivering a cinematic and powerful bass experience that can be felt as much as heard.

Sound Quality and Build

Owners consistently laud the Sonos Sub 4 for its exceptional audio performance, reflected in its high Immersive Sound score of 9.0/10. Reviewers frequently highlight the subwoofer's deep, cinematic bass that is both rich and powerful, often described as "room-shaking" and "heart-thumping." Many report that it brings movies, music, and games to life, creating an "unreal" soundstage that rivals high-end theaters. The dual Sonos-engineered drivers are praised for producing clean, distortion-free bass, with several owners noting the absence of buzz or rattle even at high volumes. This robust performance is a testament to its solid Build Quality, scoring 8.0/10, with owners consistently remarking on the high-quality audio output and the system's ability to provide pure, non-saturated bass that can be adjusted to personal taste. One owner even stated it "slaps hard for being so small and compact," while another found it comparable to a 12-inch subwoofer from an older system.

Setup and App Experience

The Ease of Setup for the Sonos Sub 4 earns a high score of 8.5/10, with numerous owners reporting a "breeze" of an installation process. Many simply plugged in the power cable, opened the Sonos app, and had the subwoofer integrated into their existing system within minutes. The wireless design is a significant advantage, offering flexible placement options without the need for additional cables. The Sonos app, while receiving a moderate App & Ecosystem Functionality score of 7.0/10, is generally appreciated for its ability to recognize and configure devices, assign them to specific rooms, and integrate various music services. Some users found the app intuitive for fine-tuning sound to fit their room, and the Trueplay tuning feature was highlighted as a valuable tool for optimizing audio. A few owners mentioned that the app and software could be improved, but this did not detract significantly from their overall positive experience with the product's core functionality.

Connectivity and Compatibility Concerns

Despite its strengths, the Sonos Sub 4 faces some challenges in Connectivity & Ports (7.5/10) and Compatibility Experience (6.0/10). Several owners reported difficulties connecting the subwoofer to their Wi-Fi networks, with some experiencing complete failure to connect or needing to troubleshoot for extended periods. Connectivity issues were particularly noted in environments with community internet or when attempting to integrate a large number of Sonos devices. A more significant concern for some buyers was the subwoofer's compatibility. Multiple reviews indicated that the Sub 4 is not compatible with certain older Sonos components, such as the Playbase, leading to frustration and returns. One long-term Sonos user expressed disappointment over what they perceived as "planned obsolescence," as they were unable to add the Sub 4 to their existing older system without replacing other components. Additionally, while the Sub 4 can be used in a dual subwoofer setup, owners noted that both units must be Sub 4s, which can be a limitation for those looking to combine it with a Sub Mini.

Value and Final Thoughts

The Sonos Sub 4 is a premium product, and its Value for Money score of 6.5/10 reflects a common sentiment among owners: it is expensive. While many ultimately deem it "worth every penny" for the superior sound quality and immersive experience, a notable number of reviewers felt the price tag was "underwhelming" for the performance or simply "overpriced." Some even suggested a lower price point would be more appropriate. However, for those committed to the Sonos ecosystem and prioritizing high-quality, powerful bass, the Sub 4 is frequently described as an "absolute must-have" and a "perfect companion" to soundbars like the Arc Ultra. Overall, the Sonos Sub 4 delivers on its promise of deep, impactful bass and seamless integration within a modern Sonos system, but potential buyers should weigh its significant cost against their budget and ensure compatibility with their specific setup.
