Vizio S4251W-B4 Review


Until recently, sound bars have remained a frustrating audio category dominated by extremes. On one end of the spectrum, you had your inexpensive sound bars which barely performed well enough to best most built-in TV speakers. On the other, you had...

Remarkable sound quality for the money ; LCD display on remote ; Comprehensive channel controls ; Wireless subwoofer and surround signal delivery ; Multiple inputs

Short surround speaker wires ; Sub doesn’t get incredibly deep ; Volume control moves in large increments

Vizio’s S4251W-B4 delivers the sort of features and control that users have been longed after for years now, and does it with style, finesse and surprisingly good audio quality.

Vizio S4251w-B4 5.1 Channel Sound Bar Home Theater System - Review


I found that the Vizio S4251w-B4 5.1 Channel Home Theater System delivered a very good surround sound listening experience, with a prominent center channel and good left/right channel image.

Excellent alternative


Vizio has really up'd their game, I paired this with a 60"Vizio TV, has been flawless in the last year and half. Biggest complaint, the remote is too dimmed to see most of the time, other than that, great sound.

Good Value


I've been using this set up for a couple of months now and it's been great. It was really easy to set up and I have not had any issues with the signal between the sound bar and the sub and rear speakers. It sounds great for the price.

Basement Into a Home Theater


I wanted more sound for watching movies & TV in my basement. While not a large room, this does plenty for surrounding you with sound. I love the remote & Bluetooth capability as well!

Fantastic sound bar for the price


Incredible 5.1 surround sound for the price. Great for small living rooms like mine. Easy to set up and to fine tune the settings. Bass is nice. Recommend.
