The SoundBase 670 was the first home theater to deliver thunderous, theater-quality sound from a single, slim cabinet. Only 3.5” high, it includes three built-in powered subwoofers, an awesome 105-watt Class D digital amplifier, five high-performance speakers, Dolby Surround Sound, PhaseCue Surround Sound and Bluetooth aptX wireless music streaming! No messy speaker wires. No external speakers or subwoofers. Just place it on furniture, and place your 40-65” TV on top.* Connect one wire to your TV, plug it in, and you’re in business. Slim. Powerful. Elegant. Simple. (*TV base/pedestal should be 35” wide or less.)


Sound & Vision magazine gave the SoundBase 670 its "Top Pick" Award - reserved only for the best of the best. They said "Going back to the helicopter crash and lodge explosion scene in Skyfall, the SoundBase.670 had especially impressive bass. It wasn’t so much in how loud or deep it was, but the definition and tightness made it easy to separate the chop of the helicopter rotor from the roar of each explosion and the swell of the strings in the orchestral score. The ZVOX was an all-around great performer and the most fully featured soundbase in this roundup."


ZVOX's proprietary AccuVoice technology literally lifts voices out of the sound track - and then modifies the voices using hearing aid technology. We have never heard dialogue this clear and sharp. You'll hear every word, even on poorly mixed programs or British programs. CNET says “Great for folks who have trouble hearing the TV.”


If you've ever been blasted out of your chair by a too-loud commercial - you'll love our Output Leveling (OL) feature. Just push the OL button and a sophisticated processor takes over, making soft sounds louder and loud sounds softer, so there are fewer jarring moments when switching channels or when commercials come on. This system also helps by boosting the audio levels from a DVD or Blu Ray player that are not loud enough.


Great Sound.
The 570 The 670 uses a new amplifier design with extremely accurate frequency response and creates a warm, natural sound and surprisingly powerful bass. .

PhaseCue® Virtual Surround Sound.
ZVOX's proprietary PhaseCue virtual surround processing gives you rich, three-dimensional sound with movies or music. Sound & Vision magazine calls it "remarkably ingenious."

Built-In Bluetooth Wireless Audio.
The system includes high quality Bluetooth wireless streaming. It includes aptX, which allows for the best possible sound quality via Bluetooth.

Green Design.
The 670 uses a highly-efficient 105-watt Class D digital amplifier. Even playing at quite loud volumes, it usually uses less than 10 watts of total power. And standby power usage tends to be around 0.1 watts - making it one of the "greenest" audio systems ever made.

Disappearing Display.
The 670 features a four-digit display located behind the speaker grille that shows the current setting for volume, bass, treble and PhaseCue® (virtual surround) - and also shows when you have engaged the Mute, Output Leveling (OL) or AccuVoice (ACCU) features. A few seconds after you stop using your remote (or front panel) controls, the display disappears completely.

Wood (MDF) Cabinet.
The 670 features a hand-built cabinet of heavy MDF. Its low-profile design blends perfectly with flat-panel TVs up to about 65" in size (depending on the style of base used by the TV).

Performance is great. The Accu voice feature is definitely worth it if one has any kind of hearing loss. Installation had challenges and some room for improvement: Instructions were very good but it would have helped if they included steps for someone who may include a receiver in their system set-up. The power cord on the back of the sound base sticks out too much so it increases the depth required. That was a problem for us. The optical connector feels less secure than one would like.

zvox soundbar

We absolutely love this. My husband has impaired hearing and this really helped him to actually be able to hear dialog again. He's so happy with this, I just wished we'd have found it 2 or more years ago!!

Wonderful! Highly recommended.

The SoundBase 670 exceeded expectations. There is very good vocal clarity as well as full sound with nice bass for movies and musical concerts. I have a very nice 7- channel surround sound system which I haven't used since getting the 670.
