10 Best Wireless Subwoofers 2025 in the United States

The Bose Sub 2 Powered Bass Module is designed to enhance the bass performance of your portable PA system or loudspeakers. With a frequency response reaching down to 37 Hz, it delivers deep and powerful bass, making it suitable for various audio setups. The 600-watt power output provides substantial volume and clarity, supported by a unique 10” × 18” high-excursion RaceTrack driver that rivals traditional 15” woofers in performance, yet in a more compact design.

This compactness and small footprint make it portable and easy to place in different environments. The build quality is robust, typical of Bose products, ensuring durability and longevity. Connectivity is versatile, with XLR technology and compatibility with both Bose L1 Pro32 systems and other powered loudspeakers via line input and output with selectable crossover modes.

You can also stack multiple Sub2 units for enhanced bass and use the Cardioid Mode to direct bass out front and reduce feedback. The independent sub level control knob allows for easy adjustment of bass levels according to your preference. However, potential users should note that it requires an input voltage of 120 volts, which might limit its use in regions with different power standards. Despite this, the Bose Sub 2 is an excellent option for those needing a powerful, flexible, and high-quality subwoofer for their sound systems.

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.
