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).

A Great Soundbar With Lots of Bass and Treble!

Actually, I haven't had the time needed to set this one up in my home. I do own two of these 670 models already! I am completely sold on their build quality as well as their sound quality! And even in their standby setting, they only use .1 Watts of power! When playing quite loudly they use about ten Watts. They are amazing and I am looking forward to getting this one set up in the master bedroom. Thank you for building a such a great product!

Soundbase 670 - GREAT SOUND

Fixed new home acoustic issues

In my old home, the soundbar I had was fine. Small room, lots of furniture. In my new home living room, not so much. Larger space, high ceiling, lots of wall area, less furniture. New conditions made for muddy sound. The Soundbase 670 with AccuVoice fixed all that. I don't need to set the volume nearly as high to hear/understand dialog with my 70-year-old ears. Luckily, the 670 fit perfectly in my cabinet and looks better, too. I also think the integral subwoofers of the 670 sound as good or better then the old box subwoofer (glad to be rid of that).
