Loudest Soundbar Buyer’s Guide
Audio Quality of the Loudest Soundbar
To ensure the best audio quality, our experts suggest looking for advanced technologies and auto-calibration in the loudest soundbar. Dolby and DTS technologies are among the best.
Bose models such as the Bose Soundbar 700 have clear and expansive sound using Dolby Digital plus DTS. But specific brands also have their own audio boosters such as Sony S-Force and LG Meridian for 3D sound.
Sound modes can calibrate and optimize content via the push of a button. Or, your soundbar could also automatically detect the acoustics of your room and tune itself.
Going for a soundbar with at least 96dB  and above 300W of power will ensure loud and reverberating sound.
Our audio team always suggests choosing digital over analog wired connectivity, and more specifically, HDMI. Digital connections support higher quality content and are a simple one-cable setup.
For wireless connection and streaming, a preferred soundbar can feature either Wi-Fi, Bluetooth or both.
For the loudest sound bar, an internal or external subwoofer can greatly affect the audio levels. A soundbar with a subwoofer will produce deep and rumbling bass that vibrates throughout the room.
Some high-end soundbars including Nakamichi Shockwafe Elite 7.2 have supporting rear speakers and two large subwoofers that deliver true surround sound and amazing bass.
A soundbar can come with its own remote control or be configured to work with your existing universal one. Whatever the case, having a remote control will greatly increase the convenience level.
Why Should You Get A Loud Soundbar?
A loud soundbar can deliver room-filling audio even at lower volumes. This will further ensure that you won’t need to crank up the volume to high levels and risk distortion just to make out what’s being said onscreen.
Even smaller models like the Sonos Play 1 as well as Bose Soundtouch 10 can provide room-filling audio at lower volumes.
