Sonos Beam G2 Sub Mini vs Sub 4 Specs
System Configuration
The Sonos Beam G2 + Sub Mini is sold as a complete 2-Pack entertainment set. It includes the Beam soundbar and the Sub Mini to form a full home theater pair. In contrast, the Sonos Sub 4 is listed as a Pair of wireless subwoofers. It is designed to pair with compatible Sonos speakers like the Arc Ultra or Arc. You get a dedicated subwoofer duo rather than a soundbar bundle. This makes the first option a complete audio system starter, while the second is an expansion for an existing speaker setup.
Enclosure Type
The Sonos Sub 4 features a ported enclosure design. This specific construction enhances bass response and low-frequency output for a more impactful sound. The Sonos Beam G2 + Sub Mini does not list a specific enclosure type in its published data. We only know it is a compact subwoofer intended to balance lowest frequencies. The ported design of the Sub 4 offers a clear technical advantage for deep bass reproduction compared to the unspecified design of the Sub Mini.
Frequency Response
The Sonos Sub 4 delivers bass response as low as 25 Hz. This specification indicates it can reproduce very deep, sub-audible frequencies for a cinematic experience. The Sonos Beam G2 + Sub Mini does not provide a specific frequency response range in its key specs. We only know it balances out lowest frequencies to make the Beam sound better. The Sub 4 provides a measurable advantage with its confirmed 25 Hz lower limit, offering more precise low-end performance data.
Connectivity
Both products rely on WiFi for connectivity within the Sonos ecosystem. The Sonos Beam G2 + Sub Mini also supports Apple AirPlay 2 for streaming music and content. The Sonos Sub 4 connects wirelessly to your soundbar or speaker over WiFi. It does not list AirPlay 2 support, as it is a passive subwoofer. For general system connectivity, they are tied. However, the Beam G2 set offers additional streaming versatility through AirPlay 2 for active playback.
Physical Dimensions
The Sonos Sub 4 has specific dimensions of 15.3 inches in width, 15.8 inches in height, and 6.22 inches in length. It weighs 26.5 pounds and can be stood upright or laid on its side. The Sonos Beam G2 + Sub Mini set lists heights of 4.8 inches and 2.7 inches for its components, indicating a much more compact footprint. The Sub Mini is clearly designed for smaller or medium-sized rooms. The Sub 4 is a larger, heavier unit for more substantial bass output.
Bass Technology
The Sonos Sub 4 uses dual Sonos-engineered drivers and a force-canceling acoustic architecture. This design virtually eliminates distortion, buzz, and rattle during high-volume playback. The Sonos Beam G2 + Sub Mini uses the Sub Mini to balance out lowest frequencies. It does not mention force-canceling technology or dual drivers in the provided data. The Sub 4 offers a more advanced internal mechanism for clean, distortion-free bass, which is a significant technical advantage for audio purity.
