The slim Yamaha yas-107 sound bar fits under most tvs and delivers serious sound. Serious bang for your buck I consider yamaha's so-called "Entry level" sound bars one of the best values in home theater sound. Their latest value-packed bar — the yas 107— even features dts virtual:x. This special technology simulates three-dimensional sound. This single, compact unit fits right under your screen on your tv stand or mounts on your wall. Don't let the modest price and super-slim design fool you. Yamaha's powerful drivers and special surround processing give you a large, riveting sound experience. Everything sounds bigger and clearer — effects, dialogue, and music, too. How does dts virtual:x work? Many sound bars simulate dolby atmos or dts:x by bouncing sound off your walls and ceiling. That's not what's happening here. The drivers inside the yas-107 sound bar are slightly angled, but they're placed more or less where you'd expect to find them in two-channel bar. There are no upward-firing drivers. Instead, dts virtual:x almost completely relies on digital sound processing. Dts uses what they call "Spatial audio techniques" to — my word here — "Trick" you into thinking you're hearing sound all around you. Incredibly sophisticated audio delays and adjustments create a larger, wider soundstage. That includes overhead atmospheric effects like leaves rustling on a tall tree or birds chirping above. Read my article "What is dts virtual:x?" for more details Binge-watch with better sound The yas-107 includes dolby® and dts® decoding as well as yamaha's digital surround processing. Built-in amplifiers power six drivers for rich, full-range sound, with plenty of high-frequency detail. From soft footfalls to jarring collisions, the slim bar adds visceral realism to your favorite movies and shows all by itself. Bu if you crave even more bass impact, there's a dedicated output for adding an optional powered subwoofer. Bluetooth lets you play tunes wirelessly Yamaha didn't forget the music — after all, it's how the company made their name. The yas-107 has built-in bluetooth so you can play music wirelessly from your phone or tablet. Special processing cleans up compressed audio files, so all your tunes will sound full and detailed. Easy hookup and operation Both hdmi connections are 4k compatible, with full hdcp 2.2 capability — so it will work with 4k tvs with high dynamic range (hdr). You can also use the included optical digital cable to connect the sound bar to your tv. Use your existing tv remote to control power and volume commands, use the included remote, or download the free yamaha home theater controller app. This turns your apple® or android™ device into a bluetooth remote.
