Vizio SB4021M-A1 Review


Vizio SB4021M-A1 reviews roundly agree that this home theater system is an excellent value, producing better sound than one would expect from such a low-priced model. The subwoofer adds depth to movies without being too "boomy," asserts a Vizio SB4021M-A1 review at Digital Trends. And while this sound bar doesn't provide a completely convincing surround sound effect, a Vizio SB4021M-A1 review at Home Theater Review continues, it boasts a very wide sound field and the bass delivers big time. Indeed, this expert expresses surprise at the high quality of the sound given the bargain price. Gadget Review also likes the power of the bass, which doesn't overpower the other speakers, and notes that midrange tones are accurate and there's no hissing or distortion at high volumes. The sleek design attracts comment in a Vizio SB4021M-A1 review by Home Theater Review, which also reports that the bass from the subwoofer really pops during movies. We read a grumble here and there about the absence of Bluetooth support, which is available on more and more home theater systems.

The Vizio SB4021M-A1 (starting at $221, Amazon) is a 40-inch sound bar that consists of two speakers plus a subwoofer. This system supports Dolby Digital, SRS TruVolume, and SRS TruSurround, which helps to create a surround sound effect. For connections, the Vizio SB4021M-A1 offers a digital optical input, a coax digital input, a 3.5mm input, and a USB 2.0 port. Of course, a remote control is part of the package.

This home theater system from Vizio doesn't include lots of components, but it doesn't need them. The speakers deliver good sound and the subwoofer strikes just the right balance of power and depth without overshadowing the speakers. And the price of this system is hard to beat. If you already have a Blu-ray player and simply need speakers for the finishing touch, this option is hard to ignore.
