10 Best Wireless Subwoofers 2025 in the United States

The Sonos Sub 4 wireless subwoofer is designed to enhance your home audio experience, especially when paired with Sonos soundbars like the Arc Ultra, Arc, or Beam. One of its major strengths is the dual Sonos-engineered drivers that produce deep and rich bass, making it ideal for movie and music lovers seeking immersive sound. The ported enclosure further boosts low-frequency output, adding to its ability to deliver powerful bass without distortion, thanks to its force-canceling technology that minimizes unwanted noise and rattling.

When it comes to connectivity, the Sub 4 uses Wi-Fi, which provides a reliable connection to your Sonos system. This eliminates the clutter of wires and allows for flexible placement options, whether you choose to stand it upright or lay it on its side. Setting it up is quite simple too; you only need to plug it in and use the Sonos app.

In terms of design, the Sub 4 features a sleek, sculptural look with a matte finish that can blend well with modern decor. Its portability is another advantage, weighing around 26.5 pounds, making it manageable for most users. However, the Sonos Sub 4 isn't without its drawbacks. While its Wi-Fi connectivity is a plus for wireless setups, it may lead to issues if your home network experiences disruptions. Additionally, it's not waterproof, which could be a concern in environments prone to spills or high humidity. Lastly, while it excels at bass performance, those who prefer a more balanced sound profile across different frequencies may find it less ideal for their listening preferences.

The Sonos Sub 4 is best suited for individuals looking to enhance their home theater experience with powerful bass, especially in a Sonos system. Yet, potential buyers should consider their connectivity needs and environmental conditions before purchasing.

The Polk Audio Signa S2 Sound Bar & Wireless Subwoofer excels in several areas essential for wireless subwoofers. Its frequency response up to 20 KHz ensures a wide range of sound reproduction, which is great for enjoying various types of audio content, from movies to music. The 25 Watts maximum output power might seem modest compared to higher-end models, but it is sufficient for most home theater setups, especially when supplemented by the wireless subwoofer that provides rich, deep bass.

The ultra-slim design of the sound bar, standing just over 2 inches tall, makes it versatile for placement, either mounted on a wall or positioned in front of your TV without obstructing the view or remote signals. Connectivity is a strong point for this system, offering HDMI ARC, optical input, AUX, and Bluetooth, which means you can easily connect it to various devices and stream music wirelessly.

Despite these strengths, some users might find the build quality to be more mid-range, with plastic components that, while functional, may not offer the same premium feel as more expensive models. Additionally, while the sound bar includes five full-range drivers that deliver robust sound, serious audiophiles might feel the need for more power or additional sound customization options. Nonetheless, for those looking to upgrade their home theater experience with a focus on ease of setup, good sound quality, and versatile connectivity, the Polk Audio Signa S2 is a strong contender.

The Sonos Sub Mini is a compact wireless subwoofer that fits into the home audio category, making it ideal for users looking to enhance their entertainment systems with deep bass. One of its standout features is the dual custom 6-inch woofers, which produce low frequencies that rival larger subwoofers without taking up much space. The force-canceling design minimizes distortion, ensuring that your audio remains clear and powerful. The advanced Trueplay tuning technology adjusts the bass output to suit your room's acoustics, reducing the chance of harsh or muddy sound, which is a great advantage for users concerned about placement flexibility.

In terms of connectivity, the Sub Mini operates over Wi-Fi, allowing for seamless integration with other Sonos products like the Beam or Ray. This makes it a fantastic option for those already invested in the Sonos ecosystem or looking to create a multi-room audio setup.

There are a few drawbacks to consider. The requirement of a compatible iOS device for Trueplay tuning might limit some users, especially those who prefer other operating systems. Additionally, while the Sub Mini's power output of 250 watts is impressive, it may still lack the thunderous impact of larger subwoofers for users seeking extreme bass for genres like hip-hop or electronic music. Lastly, its indoor usage limit means it won't be suitable for outdoor gatherings.
