Design and Build
The VIZIO SB46514-F6 system adopts a straightforward, home theater-centric design with a focus on functional speaker placement. The main sound bar measures 46 inches in length, which requires consideration for placement beneath or in front of a television of comparable size. Its enclosure is constructed from plastic, housing a sophisticated array of drivers including tweeters, mid-bass drivers with neodymium magnets, and passive radiators for the front channels. The most distinctive design element is the integration of four upward-firing speakers—two in the main bar and one in each rear satellite—which are angled to reflect sound off the ceiling to create the overhead audio effect essential for Dolby Atmos.
The wireless subwoofer features a 10-inch driver in a ported enclosure, designed to be placed anywhere in the room for optimal bass response. While the subwoofer connects wirelessly to the sound bar, the two rear surround speakers are not wireless; they require a physical wired connection to the subwoofer unit for power and audio signal. This semi-wireless approach offers placement flexibility for the bass module but necessitates cable management for the rear channels. The system comes in a uniform black finish, maintaining a low-profile aesthetic that blends with most home entertainment setups. All necessary cables for setup are included in the box.
Performance and Features
Audio Performance and Immersion
The core performance claim of the SB46514-F6 is its ability to deliver true multi-dimensional, cinematic audio. With a 5.1.4 channel configuration and ten total amplifier channels, the system is engineered to decode and play object-based audio formats like Dolby Atmos. The four upward-firing speakers are critical here, designed to produce the height channel effects that place sounds like rain or aircraft above the listener. The system also supports DTS Virtual:X, which can simulate a three-dimensional soundfield from standard stereo or surround content, adding versatility. A dedicated center channel within the sound bar is tuned specifically for dialogue clarity, a boon for movies and TV shows.
According to the manufacturer’s specifications, the total system can achieve a sound pressure level (SPL) of 108 dB, indicating a capability for high volume output with low distortion. The frequency response is listed as 20 Hz to 20 kHz, suggesting the wireless 10-inch subwoofer is tasked with delivering the lowest bass frequencies. The use of neodymium magnets in the drivers typically allows for more powerful and efficient sound reproduction in a compact form factor. The quad-core digital signal processor (DSP) handles audio decoding and room optimization tasks.
Connectivity and Inputs
Connectivity is a strong suit for this system, offering multiple ways to integrate it into an entertainment setup. For the best audio quality and ease of use with modern TVs, it features an HDMI ARC (Audio Return Channel) port. This allows a single HDMI cable to carry audio from the TV to the sound bar and enables control via the TV remote. An optical digital audio input (TOSLINK) is provided for older televisions or other devices. There is also a USB port, though its specific supported functions (e.g., media playback) are not detailed in the provided specifications.
For wireless audio, the system is equipped with dual-band built-in Wi-Fi and Bluetooth. The Bluetooth range is specified as 10 meters. The Wi-Fi connectivity enables the system’s smart features, primarily Chromecast built-in. This allows users to stream audio directly from compatible music services like Spotify, Pandora, and Google Play Music over the network, which can provide higher quality than Bluetooth streaming. The inclusion of both wireless protocols offers significant flexibility for content sources.
Smart Features and Control
The VIZIO SB46514-F6 incorporates several smart features that extend its functionality beyond a simple audio output device. It is officially compatible with voice assistants, specifically the Google Assistant, allowing for hands-free voice control when paired with a Google Home device. Control methods also include the included physical remote control and the VIZIO SmartCast Mobile app, which must be downloaded to access the full suite of Wi-Fi streaming and system settings. The app turns a smartphone or tablet into an advanced remote, facilitating music streaming from various services and potentially system adjustments. The system does not have a built-in MP3 player.
Setup, Support and Ownership
Who Should Buy It (and Who Should Skip It)
The Vizio SB46514-F6 is ideally suited for home theater enthusiasts who desire a significant audio upgrade from TV speakers or a basic sound bar and are specifically seeking the immersive, overhead effects of Dolby Atmos. It’s a great fit for those who want a powerful, multi-channel system but wish to avoid the expense and complexity of a traditional AV receiver and separate speaker setup. Users who prioritize clear dialogue in movies and enjoy deep, impactful bass from a wireless subwoofer will find its performance aligned with their needs. Its streaming capabilities also make it a good choice for households that enjoy multi-room music via Chromecast.
This system may not be the best choice for everyone. Those with very limited space should note the 46-inch width of the main bar. Users who desire a completely wireless rear speaker setup might be disappointed, as the rear satellites require a wired connection to the subwoofer. Individuals who prefer not to use a smartphone app for full functionality might find the SmartCast requirement a minor inconvenience. For those seeking simpler, more compact sound bar solutions without height channels, exploring other options like the best TV soundbars for voice clarity or best Wi-Fi soundbars could be beneficial.
Final Verdict
The VIZIO SB46514-F6 stands as a feature-packed and ambitious sound bar system that successfully packages advanced object-based audio technology into a consumer-friendly format. Its core strength lies in delivering a legitimate 5.1.4 Dolby Atmos experience with actual upward-firing speakers, a configuration that was once exclusive to high-end separates. The powerful wireless subwoofer and dedicated center channel address two common home theater desires: deep bass and clear dialogue. The breadth of connectivity options, from HDMI ARC to Chromecast, ensures compatibility with a wide range of modern and legacy devices, making it a versatile hub for both movie and music playback.
Potential buyers should weigh the system’s physical requirements and semi-wired nature of the rear speakers against their room layout and preferences. While it offers a simpler setup than a full receiver-based system, it is not as minimalist as a single-bar solution. For the target audience—those seeking a transformative, immersive audio experience for movies and games without delving into custom installation—the VIZIO SB46514-F6 represents a compelling and capable choice. It brings a taste of premium cinematic sound into the home, backed by a standard one-year warranty.

FAQs
Does the Vizio SB46514-F6 have truly wireless rear speakers?
No, the rear surround speakers are not completely wireless. While the subwoofer connects wirelessly to the sound bar, the two rear satellite speakers require a physical wired connection to the subwoofer unit for both power and audio signal transmission. This means you will need to run cables from the subwoofer’s location to where you place the rear speakers.
What is needed to use the Wi-Fi and smart features?
To access the Wi-Fi streaming, Chromecast built-in, and advanced settings, you must download the free VIZIO SmartCast Mobile app on a compatible smartphone or tablet. The system uses this app for network setup and to stream music from supported services over your home Wi-Fi network. Basic functions can be controlled with the included remote.
Can this sound bar be mounted on the wall?
The mounting type is listed as “Sound Bar” in the specifications, which typically indicates that the main unit is designed for placement on a surface in front of the TV or can be mounted on a wall using a compatible bracket. The manufacturer’s documentation would provide specific details on mounting hardware and requirements, which are not included in the provided data set.
How does the Dolby Atmos effect work without ceiling speakers?
The system creates the Dolby Atmos height effects using four upward-firing speakers—two in the main sound bar and one in each rear satellite. These speakers are angled to project sound toward the ceiling, which then reflects down to the listening position. This reflected sound creates the illusion of audio coming from above, simulating the effect of dedicated in-ceiling or height speakers.
