VIZIO 5.1 Soundbar (SV510MW-0906) Review: The SB4051-D5's Successor
The VIZIO SB4051-D5 was a 5.1 home theater system: a 40-inch soundbar, a slim wireless subwoofer and two rear satellite speakers. VIZIO no longer sells it. The closest current model in VIZIO’s lineup is the VIZIO 5.1 Soundbar (SV510MW-0906), which keeps the same bar, subwoofer and rear speakers layout. This review covers that model and how it compares with the one it replaces.
Updated September 2026: product availability, specs and prices re-checked.
VIZIO 5.1 Soundbar (SV510MW-0906) Design and Build
The system has four pieces: a 33-inch soundbar, a wireless subwoofer and two wireless surround speakers. The bar is about 7 inches narrower than the 40-inch SB4051-D5.
The soundbar measures 33 x 2.32 x 3.33 inches and weighs 4.81 pounds. It contains three full-range drivers, one each for the left, center and right channels. The subwoofer is 6.61 x 7.65 x 11.10 inches with a single 5-inch driver, so it is easy to hide but limited in deep bass.
The surround speakers are small cubes, about 3.15 x 4.45 x 3.15 inches, with two 1.87-inch drivers each. On the old system the satellites were wired to the subwoofer. Here they connect wirelessly to the bar, but each one still needs its own power adapter and a nearby outlet. VIZIO recommends keeping them within 20 feet of the bar and at or above ear level.
The bar can be wall mounted with the included brackets or attached to the bottom of select VIZIO TVs using QuickFit, VIZIO’s tool-free mounting system.
VIZIO 5.1 Soundbar Review: Features
Dolby Atmos and DTS:X
The SB4051-D5 decoded Dolby Digital and DTS, with DTS TruSurround and TruVolume. The new model decodes PCM, Dolby Digital and Dolby Digital Plus, DTS, DTS:X and Dolby Atmos. VIZIO also lists DTS Virtual:X, DTS Studio Sound and DTS TruVolume. There are no up-firing drivers, so the height effect in Atmos content is virtual.
Flexible Surround Placement
Because the surrounds are wireless, placement is easier. The app offers three surround settings. Off plays sound from the bar and sub only. Dual makes the surrounds mirror the bar. Front is for rooms where the speakers must sit beside the soundbar instead of behind the couch.
App Control Instead of a Remote
The SB4051-D5 shipped with a remote. The new system does not. The TV remote handles power, volume and mute over HDMI-CEC. Everything else is in the VIZIO mobile app: Movie, Music and Direct modes, bass, treble, subwoofer level, ClearDialog and Night Mode. VIZIO’s soundbar pages say the app and an account are required to change settings and install updates. A VIZIO soundbar remote is sold separately.
Connectivity
Connectivity is much simpler than on the SB4051-D5, which offered several wired inputs plus Wi-Fi with Google Cast built in. The new bar has one HDMI eARC port to the TV, Bluetooth 5.3 and a USB port for WAV and MP3 files. There is no optical input, no HDMI passthrough and no Wi-Fi streaming. If your TV lacks an HDMI ARC or eARC port, this system is not a good fit.
Performance
VIZIO rates the system at 96 dB maximum sound pressure level, with a frequency response of 45Hz to 16kHz (plus or minus 5dB).
We did not find an independent lab review of this exact model. RTINGS did review the closely related 5.1 Soundbar SE (SV510X-0806), which uses the same bar-plus-sub-plus-satellites layout. Its reviewers found dialogue clear thanks to the dedicated center channel, and the surround effects immersive. They also noted that the compact sub adds punch but does not reach deep sub-bass, and that boosted bass can muddy the midrange. On VIZIO’s site, owners rate the SV510MW-0906 4.4 out of 5 as of September 2026.

Conclusion
The SB4051-D5 is no longer sold. For the same idea of a complete 5.1 system from VIZIO at a modest budget, the 5.1 Soundbar (SV510MW-0906) is its current equivalent. It adds Atmos and DTS:X decoding and wireless surrounds, but gives up the old model’s remote, Wi-Fi casting and wider range of inputs.
It makes the most sense for a small or medium room and a TV with HDMI ARC or eARC. If you need optical input or stronger bass, compare it with larger systems before you buy.
