ZVOX SoundBase 570

The ZVOX SoundBase 670 supports TVs up to 70".

A simple concept that works

The ZVOX SoundBase sits right on top of whatever surface holds your TV, and your TV sits right on top of the SoundBase — simple, effective, and easy. The 670 works with most TVs that have 70" or smaller screens, weighing up to 120 pounds. Just like many other sound bar systems, the this one connects to your TV using a single cable (optical digital and analog RCA audio cables are included). The system's built-in 105-watt Class D amplifier puts out plenty of power to drive the built-in speakers to impressive volume levels. Bluetooth wireless streaming is new on this year's SoundBase models: pair your tablet or smartphone and enjoy rich, full sound with your favorite tunes.

Product Research


SoundBase 670: The ZVOX SoundBase 670 speaker system is designed to sit beneath your flat-panel TV so you can have surround sound without adding a lot of clutter to your room. It requires no additional speakers, subwoofer, or speaker wires. The SoundBase 670 reproduces TV shows, music, and movie soundtracks with lifelike accuracy, including crystal-clear vocals and big bass. The ZVOX SoundBase 670 is the perfect solution for people who want great sound from their flat-panel TV without the clutter and complexity of a conventional home theater system.

Note: You can place the ZVOX SoundBase 670 directly beneath most 40"-65" flat-panel TVs weighing up to 120 lbs with a pedestal base which does not exceed 29" in width or 15" in depth. The SoundBase 670 has a height of only 3.5". You can also place the SoundBase 670 on a shelf under most table-top or wall-mount flat-panel televisions.

Advanced Speaker Design: The ZVOX SoundBase 670 speaker system incorporates high-quality speakers, built-in subs, a highly efficient amplifier, and digital signal processing for high-fidelity sound. And its all packed inside one slim, compact enclosure.

  • 5 Speaker Array w/ Built-in Subwoofers: The ZVOX SoundBase 670 speaker system includes five front-firing 2"x3" full-range drivers and three down-firing 5.25" subwoofers. The 2"x3" full-range drivers use a long-throw design to create a remarkably wide range, accurate sound. The triple 5.25" subwoofers use a high-mass long-throw design and are coupled with a rear-firing port for deep, accurate bass.
  • Class D Amplifier w/ DSP:  The ZVOX SoundBase 670 employs a highly efficient 105W Class D amplifier that includes digital signal processing (DSP) for superb frequency response. The result is a very warm, natural, smooth, and accurate sound.
  • MDF Cabinet: The 670 features a hand-built cabinet of heavy MDF. The speaker cabinet is robustly constructed using fully-braced MDF (medium density fiberboard), not molded plastic that is found any many lesser expensive soundbar speaker systems. MDF is the preferred construction material for high-performance speaker systems.

PhaseCue II Virtual Surround Sound: The SoundBase 670 uses ZVOX's proprietary PhaseCue II virtual surround processing to give you rich, three-dimensional sound with movies or music. PhaseCue II, as its name implies, manipulates the phase of the separate channels to "fool the ear" into believing that sound is coming from a variety of sources throughout the room. The benefits of PhaseCue II vary greatly based on program material. Live music and well-recorded modern movie soundtracks will deliver rich, three-dimensional sound - pulling the sound out from the speakers and into the room, virtually surrounding the listener.

  • Music: With music, PhaseCue II creates a very wide soundstage - it literally sounds like you are listening to speakers eight feet apart from each other.
  • Movies: When listening to a good movie, the soundtrack will envelop you - putting you in the middle of the action.
  • Levels: You can adjust the level of PhaseCue II virtual surround processing effect. You can select from Surround One (low effect), Surround Two (moderate effect), Surround Three (strong effect).
Note: AccuVoice cannot be used in conjunction with a PhaseCure Virtual Surround Sound mode

Audio Enhancement: The ZVOX SoundBase 670 offers a variety of audio adjustment to enhance your listening experience.

  • AccuVoice: The SoundBase 670 includes the ZVOX AccuVoice feature, which uses hearing aid technology to create super-clear voice reproduction. When you push the "ACCU" button on the remote control you engage a circuit that mimics the functions of a hearing aid. The frequencies used by human voices are dynamically emphasized, while other frequencies are minimized.
  • Output Leveling: The SoundBase 670's Output Leveling feature automatically turns down loud commercials, while boosting audio levels from DVD and Blu-ray movies that are not loud enough. Simply press the "OL" button on the included remote 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.
  • Tone Control: The SoundBase 670 has independent bass and treble controls. Each has a range from -4 to 4, and can be adjusted using the remote control only.
Note: AccuVoice and Output Leveling can be activated simultaneously.

Wired & Wireless Connectivity: The ZVOX SoundBase 670 offers wired and wireless connectivity; including digital and analog inputs, Bluetooth audio streaming, and a subwoofer output.

  • Digital & Analog Inputs: The SoundBase 670 has two optical (toslink) digital inputs and one coaxial digital input, plus two analog stereo RCA audio inputs on the rear-panel. Plus, there is a front panel analog stereo minijack (3.5mm) input for convenient connection of a portable audio device. The three digital inputs will support both 2ch PCM and Dolby Digital 5.1ch audio. The analog inputs only support 2ch PCM.
  • Bluetooth Wireless Audio + aptX: The ZVOX SoundBase 670 supports Bluetooth A2DP which allows you to wirelessly stream audio from your Bluetooth-enabled Apple iPod/iPhone/iPad, Android smartphone/tablet, Blackberry, laptop/computer, etc.. You'll be able to stream stored music or music apps from your Bluetooth-enabled device to the SoundBase speaker system. The SoundBase 670 even employs AptX audio coding technology for lossless, CD-quality streaming with compatible AptX-compatible phones (like some Androids OS 4.0+). You will continue to use your Bluetooth-enable mobile device for music navigation and to view song/artist information.
  • Subwoofer Output: An optional powered subwoofer can be connected using the full-range mono-RCA Sub Output on the back panel for even bigger bass. There is no low-pass crossover built-in to the sub out, so you will need to set the low-pass crossover of your powered subwoofer accordingly.

Hidden Display: The ZVOX SoundBase 670 features a four-digit display located behind the speaker grille that shows the current setting for volume, bass, treble, and PhaseCue II (virtual surround); plus shows when you have engaged the Mute, Output Leveling (OL) or Dialog Emphasis (DE) features. A few seconds after you stop using your remote (or front panel) controls, the display disappears completely.

Remote Control: The ZVOX SoundBase 670 comes with an IR remote control for wireless operation of the system. The included wireless remote has controls for power, input select, mute, volume, PhaseCue II effect level, bass & treble level, and DE/OL functions. The SoundBase 670 can also be programmed to respond to your TV or satellite/cable remote control. Once programmed, you can control volume, mute, input, and power with your TV or satellite/cable remote.

Note: Many newer TVs are coming with RF remotes and don't offer IR functionality. In this case, you would not be able to program the soundbar and TV remote to work together.

Auto On/Off: The ZVOX SoundBase 670 will automatically turn on if it senses a volume adjustment or power command from your programmed remote control or the included remote control. The SoundBase 670 will also automatically turn off if the selected input is silent for longer than approximately 30 minutes.

Customer Q&A

Crutchfield asked: Why did you buy this?
I bought an older model ZVox 450 and it is Super Awesome. But! It is not as simple a set up as claimed. I followed the instructions and had to call cust support. And as a cust here stated "they are not the most patient and helpful" of people. I think maybe they need more fiber in their diet. But i have a new tv and the speakers are anemic and i wanted a new ZVox base so i can enjoy my movie channels. With Z you can actually hear the voice clearly amongst the other clear background sounds! [ patrick e.  Oct 04, 2019 ]
I need a soundbar platform to be able to hear the TV more clearly. The description said this was the thing to have. I hope so! [ AARON  Jul 06, 2019 ]
I need something to help hear dialog, this got great reviews for that. [ D  Feb 11, 2019 ]
This is a simple way to get home theater sound out of my new flat screen tv with out any of the clutter that comes with conventional speaker set ups. The zvox 670 was highly recommended by a friend. [ Jesse  Dec 28, 2018 ]
Our tv is located in the corner of the room and the SB400 was too tall to put on the cabinet in front of the tv. The SB670 was perfect for our 50in tv to set on. [ Chuck  Nov 22, 2018 ]
Platform design, reviews on-line, customer feedback - especially about the enhanced dialogue. [ Robert  Sep 27, 2018 ]
I bought a ZVOX sound base years ago. I loved it, but the volume control was not great. It seemed to have two volumes, soft and loud. I recently bought a sound base and the accuvoice sound bar for two TVs. ZVOX has taken great sound and improved it with seemless integration with my TV, Accu Voice, and Output Leveling. So I had to buy one more for the TV in the basement. I love these sound bases. [ Doug  Mar 02, 2018 ]
Accuvoice technology. [ Jonathan  Dec 26, 2017 ]
I chose the ZVOX because of past experience with the brand - all positive. I chose the 670 because its dimensions fit my needs. My Samsung TV badly needs sound improvement. Time will tell. [ RALPH  Dec 11, 2017 ]
hoping it has more balanced/natural sound than a thin soundbar with separate subwoofer. Better for music, without having to pay 500+ [ DUANE  Nov 24, 2017 ]
We recently purchased a ZVOX Soundbase for our home, and like the easy installation and sound it produces. This purchase is for one of our sons. [ RICHARD L  Nov 21, 2017 ]
Was looking for a sound bar for the bedroom Panasonic plasma display and decided on the ZVOX SoundBase 670 as this company has been making sound bars for a long time and has a good reputation. I liked the idea that it's a soundBASE and my display can sit right on top of it. Makes for an easy peasy setup in a bedroom environment. Also liked getting $40.00 off the price! [ Rudolph  Nov 19, 2017 ]
to upgrade from the 555 model. [ ROBERT  Oct 17, 2017 ]
Kay was very helpful Thank you [ david  Oct 11, 2017 ]
Looks like it will work well fro my Father. Compact and simple. [ M  Oct 01, 2017 ]
To hear voice on tv. Got good reviews. [ Stephen  Aug 13, 2017 ]
it has 3 built in subs and my old Vizio 2.0 only had 1 [ Leroy Adams  Jul 28, 2017 ]
Best sound bar value. It has a variety of legacy connections and Bluetooth. [ Tiago  Dec 12, 2016 ]
Purchased Zvox 555 several years ago, and have been happy with it. [ Mark  Dec 02, 2016 ]

Perfect size for my use....Clear voice is the best for someone hard of hearing. This is my 2nd Zvox product. [ William  Jul 02, 2016 ]
great reviews on product. 60 day return policy. well informed sales help, SAM [ joseph  Jun 19, 2016 ]
It appeared perfect for the bedroom TV. The reviews convinced me to give it a try. [ JAMES  Mar 03, 2016 ]
1) Just purchased 55inch 4K-HDTV with 36 inch wide base. 2) Senior citizen - want better dialogue audio. 3) Want better audio and surround than available with small speakers in TV. 4). Better reviews than Bose Solo 15 [ stephen  Feb 27, 2016 ]
Reviews. [ PAUL  Feb 06, 2016 ]
In reviewing your thorough description, it seemed to meet my needs, at a price point I desired, and the reviews were very good. [ Mark  Jan 18, 2016 ]
Needed a sound bar and purchased this one based on reviews to replace a Sony that only lasted 18 months. I can only hope. [ Alan R.  Dec 27, 2015 ]
As TV's have gotten thinner so has the sound. This will give any TV great sound without the complexity of a surround system. [ James  Dec 21, 2015 ]

[ SCOTT  Oct 10, 2018 ]
Not sure, though probably not.
[ Rudolph  Oct 10, 2018 ]
No. Designed in USA Made in China Info is on rear of 670
[ GARY  Oct 10, 2018 ]
Do you mean to tell me that Crutchfield can't answer that question? You guys know darn well it's made in China!!! Geeze!!
[ DAVID  Oct 10, 2018 ]
I doubt it. Almost all circuit boards and mass produced electronics are made in China. Having said that, the Zvox system works well if you want better speech rendition from your flat panel tv.
