Buying Guide: What to Look for in a Soundbar
Sound Quality and Channels
The number of channels determines how immersive the audio feels. A 2.0 soundbar, like the TCL S45H, provides clear left and right stereo sound, which is a huge step up from TV speakers. For more enveloping audio with true surround effects, consider a 3.1 or 5.1 system, but for smaller rooms or tighter budgets, a quality 2.0 model offers excellent clarity and dialogue enhancement.
Look for features like Dolby Atmos and DTS Virtual:X, which simulate height and surround sound without extra speakers. The TCL S45H includes both, adding a sense of space to your audio.
Connectivity and Compatibility
Ensure the soundbar works with your TV and other devices. HDMI eARC/ARC is the best connection for high-quality audio and control via your TV remote. Optical and Bluetooth options are useful for older TVs or wireless music streaming. The TCL S45H offers all three, plus an AUX input, making it versatile for any setup.
Bluetooth streaming is a convenient feature for playing music from your phone or tablet. For more on wireless audio, see our guide to noise-cancelling headphone deals for personal listening.
Room Size and Power
Consider the size of your room when choosing a soundbar. The TCL S45H delivers up to 100W of power, which is ideal for apartments, bedrooms, or small to medium living rooms. For larger spaces, you might want a more powerful model with a dedicated subwoofer for deeper bass.
The soundbar’s slim profile (31.89 inches wide) fits neatly under most TVs without blocking the screen or remote sensor. It’s designed to look clean and modern, not bulky.
Smart Features and Calibration
Auto room calibration can optimize sound for your specific space. The TCL S45H features AI Sonic technology that adjusts audio based on your room layout and listening position. This one-time setup through the TCL app ensures balanced sound without manual tweaking.
App control and a full-function remote add convenience, letting you adjust settings from your couch. For more home audio tips, explore our Electronics category for related reviews.
