10 Best Soundbars Under 300 2025 in the United States

The LG S90TR 7.1.3-Channel OLED evo TV Matching Soundbar is a high-performance option for home theater enthusiasts looking for immersive sound. It’s equipped with Dolby Atmos and DTS:X technologies, providing a rich audio experience. The soundbar includes rear surround speakers and a wireless subwoofer, making setup more convenient and reducing cable clutter.

The center up-firing speaker enhances dialogue clarity, which is great for watching movies and TV shows. The WOW Orchestra feature syncs audio with LG TVs, and the WOW Interface allows control of both the soundbar and the TV with one remote, which adds to the convenience. Additionally, the soundbar supports various voice assistants like Google Assistant and Alexa, and features like Chromecast and AirPlay 2, making it versatile for different users.

The built-in room calibration optimizes audio settings based on room dimensions, ensuring a tailored listening experience. On the downside, the product is relatively heavy at 44.8 pounds and large in size, which might be a concern for some users regarding placement. It is also priced on the higher end of the 'under $300' category. Despite these points, the LG S90TR is ideal for users looking for a comprehensive home theater setup with advanced sound features and integration options.

The Samsung HW-B630F soundbar is a solid choice for anyone looking to improve their home audio experience without spending too much. It offers a 3.1 channel setup, which means it has three main speakers including a dedicated center channel that makes dialogue extra clear—great for movies and TV shows where you want to catch every word. The wireless subwoofer adds good bass, giving your sound more depth and power without extra cables to worry about.

This soundbar excels in creating an immersive experience with DTS Virtual:X technology, which simulates surround sound from all around you, so you can enjoy a theater-like feel even without rear speakers. It also has adaptive sound modes that automatically adjust the audio based on what you're watching, making voices clearer or boosting effects as needed. This feature is useful if you don’t want to fiddle with settings manually. Connectivity-wise, it supports Bluetooth and HDMI, letting you easily connect up to two devices like your smartphone and TV, and switch between them smoothly. The soundbar can be controlled by your Samsung TV remote, so you don’t need to juggle multiple remotes, which keeps things simple.

The design is sleek and compact enough for most TV setups or wall mounting, and it weighs about 16 pounds, making it manageable to move around if needed. One nice touch is its gaming optimization, where sound follows the on-screen action and reduces distracting noises. A couple of things to keep in mind: it doesn’t have built-in voice assistants like Alexa or Google Assistant, so smart features are limited. Also, it’s not waterproof, so it’s strictly for indoor use. While it offers good power at 370 watts, audiophiles might find it less rich than more expensive setups with extra rear speakers. This product suits casual viewers, gamers, and music listeners looking for clear sound, decent bass, and easy control without complicated setup or extra devices.

The Polk Audio Signa S4 is a strong choice if you’re looking for a soundbar under $300 that delivers immersive, 3D Dolby Atmos sound. It features a 3.1.2 channel setup with up-firing speakers for that overhead audio effect, plus a wireless 5.9-inch subwoofer that adds deep bass, enhancing movies and music. Polk’s VoiceAdjust technology is handy for clarifying dialogue, so you won’t miss important lines, and BassAdjust lets you control the bass level to suit your taste.

Connectivity is flexible with HDMI eARC for easy setup with your TV, plus optical, analog, Bluetooth, and USB options. This means you can connect a variety of devices and stream music wirelessly from apps on your phone or tablet. The slim, compact design (just over 2 inches tall and 41 inches wide) fits well under most TVs without blocking the screen or remote sensor, and it can be wall-mounted if you prefer.

It excels in sound quality and installation ease, though the subwoofer uses a wired connection, which might limit placement options compared to fully wireless models. It also lacks waterproofing, so it’s strictly for indoor use. The included remote and voice control features add convenience but don’t offer full smart assistant integration. If you want a budget-friendly soundbar with rich surround sound, clear voice, solid bass, and multiple ways to connect your devices, the Signa S4 is a reliable pick designed mainly for home entertainment setups where wired sub placement isn’t a problem.
