10 Best Soundbars Under 300 2025 in the United States

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.

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.

However, at 42.1 pounds, it’s relatively heavy, which might be a consideration for wall-mounting. Priced at the upper end of the ‘under $300’ category, it might be a stretch for some budgets. The LG S80TR is a robust option for anyone looking to enhance their home theater or gaming experience with high-quality, immersive sound.
