Best Soundbars with Wireless Subwoofer

The Polk Audio Signa S3 soundbar, in the best traditions of the American brand, offers a set of smart technologies that will make operation simple and comfortable. The panel is compatible with the Google Home ecosystem and supports audio streaming via Chromecast technology from the most popular services — Google Play Music, YouTube Music, Amazon Music HD, Spotify, Tidal, Pandora, Deezer, Qobuz, iHeart Radio. Just connect to the home network via Wi-Fi, which will also open up access to voice control via Google Assistant. The Bluetooth module allows you to synchronize the sound projector with a smartphone and play your favorite tracks directly.

The audio system is based on 4 speakers and supplemented with a wireless subwoofer. The output creates a clear balanced sound without emphasizing a specific range, but if necessary, the user can activate the VoiceAdjust technology (3 levels) to enhance speech or choose one of the modes — cinema, night, and music. The basic Dolby Digital standard provides effect distribution between drivers to achieve surround sound. The soundbar is a universal and affordable home solution, compatible with televisions of all sizes and equipped with enhanced signal source connection capabilities.

The Sony HT-SD40 soundbar forms a powerful 300-watt audio accompaniment thanks to the X-Balanced Speaker Unit front speakers with a special design and a number of proprietary technologies. The rectangular shape increases the diaphragm area to achieve high volume, and the special Separated Notch Edge grooves ensure optimal tension and prevent distortion. The audio system is characterized by universal sound with predominant mid and high frequencies for listening to light music, watching TV programs, and movies. The voice mode allows for maximum speech enhancement, while the night mode guarantees stable volume and neutralizes sharp jumps. It is also worth noting the virtual sound distribution across channels to create a volumetric scene using S-Force PRO, although the presence of only two drivers limits this capability. The low frequencies are formed by a wireless subwoofer, which is allocated 130 watts.

The soundbar has a standard set of interfaces necessary for comfortable synchronization with sources. Wired connection is implemented via optical channel or HDMI, and direct playback of tracks from mobile gadgets is possible via Bluetooth. Source selection, mode switching, and settings are done with a remote control. The manufacturer also provided an OLED screen for visual control of parameters. It is important to note that the package does not include an HDMI cable. Owners of Bravia TVs (Sony sub-brand) will appreciate the integration of panel functions into the firmware and the ability to control with the TV remote.

The LG S70TY soundbar stands out for its advanced technical and software solutions that help adapt the sound design to the content. In addition to the standard templates (cinema, sports, games, music), the system offers special modes Bass Blast Plus, Clear Voice. Special attention deserves the AI Sound Pro intelligent algorithm, which automatically optimizes the frequency response to achieve clarity and richness of audio support. The main software assistants are the Dolby Atmos and DTS X surround sound technologies. The entire system is designed for realistic spatial distribution. To achieve this, the manufacturer uses a combination of a base and a wireless subwoofer. The main panel includes 6 front speakers and 1 vertical, which create an advanced acoustic dome Immersive 3D Spatial Sound and provide powerful sound pressure (400 W) at home theater level.

The soundbar successfully interacts with various equipment, and when synchronized with LG televisions, new opportunities open up — control with a single remote control, joint use of speakers from both devices (WOW Orchestra technology). The sound panel can also act as a gateway for transmitting video and audio from other sources via HDMI or USB inputs. Traditionally, Bluetooth is available for streaming music playback from mobile gadgets, but the company also offers an app for remote control of all soundbar settings from a smartphone (Android/iOS).

The Denon DHT-S517 soundbar embodies the company's 100-year experience in developing acoustic systems. The main advantage of the soundbar is the improved layout of speakers in format 3.1.2, which indicates the presence of two additional drivers directed upwards. This creates full spatial sound of the Dolby Atmos standard, which fills the entire room, increases the volume of the entire frequency range, and realistically transmits all events on the TV screen through precise positioning. This solution gives advantages when watching action movies and gaming. Among other things, there is a speech enhancement technology Dialog Enhancer (3 levels) without changing the overall volume, as well as a Pure mode that deactivates all preset settings and ensures playback of the original audio track in cinematic quality. The downside could be considered a small power of 80 watts, half of which goes to the sub. The system will not provide the necessary volume for large rooms and noisy parties.

The Denon DHT-S517 soundbar allows you to create a home theater without unnecessary wires. Connection to the TV is made via Bluetooth, and the external subwoofer automatically synchronizes with the base via a wireless channel. Wired interfaces are also implemented. There is an advanced HDMI eARC for high-quality sound processing and the ability to control the soundbar with a TV remote control, as well as an optical channel and an analog mini jack 3.5 mm. An additional HDMI input supports pass-through transmission of video signals in 4K resolution from external players.

The Samsung HW-S700D soundbar offers the most advanced technical solutions that guarantee comfort and functionality while watching TV, listening to music, and gaming. It is worth noting the overall high power of the audio system — 250 watts, as well as the external subwoofer, which accounts for 160 watts. It is equipped with a phase inverter for creating a richer low-frequency palette and connects to the base via Bluetooth, so it can be placed anywhere convenient in the room. The presence of Wi-Fi gives access to popular wireless services that allow data streaming via AirPlay 2 and Chromecast protocols from smartphones, tablets, laptops, and external audio devices. The company also offers flexible integration into a smart home using the SmartThings app, where you can synchronize all branded equipment and manage settings centrally. Support for Amazon Alexa voice assistant is provided.

Paired with a Samsung TV, you can create a multi-channel acoustic design thanks to the Q-Symphony technology, which unites all speakers into a single system. The soundbar itself is distinguished by good sound quality through the use of separate HF and MF drivers, as well as a number of additional solutions. The main one is the Dolby Atmos decoder, which creates rich three-dimensional sound with increased realism. Support for DTS Virtual:X provides virtual surround sound for more accurate positioning of all effects (passing vehicles, explosions, gunshots, bird singing, wind movement, and more). Another feature is the adaptive mode using SpaceFit Sound Pro technology. The system analyzes the surrounding space, optimizes the spread of the sound wave, and flexibly adapts to the content (music, TV shows, games, movies) to enhance the necessary frequencies and minimize interference. There is also intelligent speech highlighting with the Active Voice Analyzer.
