Dialogue reclaimed, commercials tamed
If you can't hear what's being said, it's nearly impossible to follow the story. That's why ZVOX created a dialogue enhancement feature that gives voices new clarity and prominence. What's more, ZVOX knows how sponsors love to blast us out of our seats when they go to a commercial break. Thanks to the Output Leveling feature, the 555 keeps commercials on a short leash so you can just relax.

Everything you need in one low-profile box
This one-piece system houses five full-range speakers, a high-output woofer, and built-in amplification — there's no need to use a separate receiver or run wires to any external speakers. Plus, the 555 is designed to serve as a convenient base for most flat-panel TVs with screen sizes from 26" to 50". Place it directly underneath your TV and you won't have to worry about making extra room for it on your entertainment stand.

Loaded with convenient features
The SoundBase 555 is a great place to plug in your iPod® or portable player for terrific sound. It has a minijack input on the front panel for easy access. Its front-panel display lights up from behind the front cloth grille then disappears when not in use. And it also learns the commands of your current TV remote, giving you one less clicker to keep track of. Signal-sensing circuitry powers the system on and off along with your TV.

The ZVOX has really improved our tv viewing. The speech on all programs, whethet movies from 30's and 40's or current sitcoms or news are clear and crisp.

Product Research



Overview: The ZVOX SoundBase 555 is a single-cabinet audio system for your flat-panel television. It combines high-quality speakers, a built-in amplifier, a built-in subwoofer, and ZVOX PhaseCue II Virtual Surround Sound processing (enhanced by a Dolby Digital decoder) to give you an easy surround sound solution. Since there are no speaker wires to deal with, you just need to connect the power and audio cables to get started.

TV Compatibility: Most 32"-50" flat-panel TVs can be placed directly on top the SoundBase 555. The television should weigh 120 lbs or less The TV's pedestal base should not exceed 27" (w) x 13.0" (d).

Class D Amplifier: The SoundBase 555 is bi-amplified, using a specially designed, highly-efficient 70 watt Class D amplifier that includes electronic contouring for superb frequency response.

Five 2" Drivers: The SoundBase 555 uses five 2.0" main speaker drivers that use a long-throw design to create a remarkable wide range, and accurate sound.

5.25" Subwoofers: In addition to the five main speakers, the SoundBase 555 has a single firing high-mass, long-throw 5.25" subwoofers in a ported enclosure.

PhaseCue II Virtual Suround Sound: The SoundBase 555 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, literally 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.
Note: While the virtual surround experience isn't the same as a high-quality 5.1-channel system, the performance is much better than the speakers built-in to most TV's.

Dolby Digital: The unit's two digital inputs work with the built-in Dolby Digital decoder for improved virtual surround performance.

Wood (MDF) Cabinet with Hand-Lacquered Side Panels: The SoundBase 555 features a hand-built cabinet of heavy MDF with beautiful hand-lacquered high gloss end panels. Its low-profile design blends perfectly with most flat-panel TVs.

Disappearing Display: The SoundBase 555 features a four-digit display located behind the speaker grille that shows the current setting for volume, bass/treble, and PhaseCue II (virtual surround). It also 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.


Dialogue Emphasis (DE): Dialogue Emphasis (DE) provides an easy-to-use and effective method for improving the intelligibility of television dialogue. By pressing the Dialogue Emphasis (DE) function button on the remote control, the system engages 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 (OL): The Output Leveling (OL) function prevents large changes in volume levels. Simply press the Output Leveling (OL) button on the remote control 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 is not loud enough.

Surround Settings: 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).

Tone Control: The bass control has a range from -8 to 4. The treble control has a range from -4 to 4.

Remote Control: The included wireless remote has controls for power, mute, volume, PhaseCue II effect level, bass & treble level. and DE/OL functions.

Programmable: The new SoundBase 555 can be programmed to respond to your remote control. The illuminated display walks you through a less-than-a-minute programming cycle. Then your TV remote, cable box remote, or satellite receiver remote can control volume, mute, power and input functions of the ZVOX system.

Auto Standby: The SoundBase 555 will enter a low-power Standby mode after approximately 5 minutes of no audio signal.


One Cable Connection: The SoundBase 555 requires only one connection cable. You can use either analog or digital connection options to your television.

Audio Inputs: The SoundBase 555 offers analog and digital audio inputs.

  • Digital Input: The SoundBase 555 is equipped with a coaxial digital (single RCA) and an optical digital (Toslink) input. The digital inputs will accept either 2-channel PCM or Dolby Digital bitstream signals.
  • Analog Input: The SoundBase 555 has two rear-panel stereo RCA analog inputs and a front-panel 3.5mm analog audio input.

Subwoofer Output: An optional powered subwoofer can be connected using the full-range single RCA Sub Output on the back panel.

Remote Control Input: This jack is reserved for ZVOX service only.

Sorry, haven't tried that. Has enough natural base "as- is" for my needs (TV only in bedroom/office space). Voice enhancement good for the seniors in the household and that's what we got it for. Our "Boom Boom" experience is from two subs on a 7:1 home theater system with the big screen in the study/lounge. That's enough of that. Good luck. [ steveinglendale  Sep 26, 2014 ]
This unit has a standard RCA output for the subwoofer, so any of the powered home subwoofers will connect with no issue. Feel free to reach out to an Advisor by phone or chat to discuss which subwoofer will be a good match for your system and the room it will be going in. [ Jeff  Nov 27, 2013 ]  Staff
