10 Best Rear Surround Speakers 2025 in the United States

The ULTIMEA Poseidon D70 is a 7.1 channel virtual surround sound system designed to enhance home theater experiences. It includes a soundbar, a 6.5-inch wireless subwoofer, and four wired surround speakers (two front and two rear), making it suitable for users seeking immersive rear-surround audio without complicated setups. With 410 watts of peak power, it delivers strong volume and clear dialogue across multiple channels, although it does not support Dolby Audio or Atmos, which might be a downside for those wanting premium surround formats.

The system offers a frequency response up to 18 kHz and a decent sensitivity level, ensuring balanced sound output for movies, gaming, and music. Its four wired surround speakers connect via long cables, allowing flexible placement in typical living rooms, though wired speakers may limit room layout options compared to wireless ones. The build quality includes a rectangular soundbar and solid subwoofer, both designed for indoor use and wall mounting, so it fits well in most home setups without taking much space.

The ULTIMEA Smart App control is a strong advantage, offering 121 preset equalizer options and 10-band tuning across various sound modes like Movie, Music, and Game. This customization helps tailor the sound to user preferences and makes it easier for non-technical users to achieve the best audio quality. The system requires setting the TV’s audio output to PCM for optimal sound and may need some initial adjustments for peak performance. In essence, the Poseidon D70 is a powerful and versatile rear-surround speaker system ideal for those looking to upgrade their home theater sound with easy app control and robust surround effects, despite lacking support for the latest Dolby formats and using wired rear speakers.

The Sony SA-RS5 Wireless Rear Speakers are designed to enhance your home theater experience by providing wireless surround sound with flexibility in placement thanks to their built-in battery. These speakers support 360 Spatial Sound Mapping, which helps create an immersive audio environment, making them a good match for Sony BRAVIA THEATER soundbars and compatible receivers. They have a wide frequency response starting at 20 Hz, which means they can reproduce deep bass tones well, contributing to richer sound effects. With a maximum output power of 180 watts, they deliver clear and powerful sound suitable for medium to large rooms.

The speakers are compact and lightweight, featuring a plastic build that is durable enough for wall mounting or flexible placement without needing a power outlet, ideal for rooms where wiring is inconvenient. The battery lasts up to 10 hours and charges quickly, but the volume is somewhat limited when running on battery power and the speakers need to be manually turned on in this mode. They don't automatically power on with battery use, which may be a minor inconvenience. Additionally, they lack waterproofing, so placement near moisture should be avoided.

The Sony SA-RS5 is well-suited for users looking for easy-to-install rear surround speakers that deliver immersive sound without the clutter of wires, especially when paired with compatible Sony sound systems.

The LG S40TR is a 4.1 channel home theater soundbar system designed to bring immersive surround sound to your living room with minimal setup hassle. Its wireless rear surround speakers and subwoofer add depth and fullness to audio, making movies, TV shows, and music feel more engaging. Thanks to Dolby Audio and DTS Digital compatibility, the sound quality is enhanced for clearer dialogue and richer bass. The system supports convenient wireless connectivity including Bluetooth, so you can easily stream audio or connect with your LG TV, especially with the WOW Interface allowing control via one remote.

The soundbar features a sleek metal and plastic build that helps protect against dust and looks modern on a tabletop. It handles power well for a mid-range system but offers only one power level, so loudness adjustments rely mostly on your remote or app controls. The rear speakers are wireless but still need placement near power outlets and aren’t waterproof, so placement options might be limited.

The LG Soundbar app lets you fine-tune bass, treble, and mid-range frequencies to suit your preferences, which is handy for tailoring sound to your room size. Clear Voice Plus technology helps ensure dialogue remains crisp and understandable, a big plus for watching movies and TV. Sized reasonably at about 28 inches wide, the soundbar fits well in most rooms without taking up too much space. This system is a solid choice for users seeking a hassle-free home theater upgrade with wireless surround capabilities and good sound enhancement features, especially if you already own an LG TV. For those wanting full speaker specs or more advanced power options, higher-end models might be more suitable.
