Most people know that to vastly improve the audio coming from your TV, you need a sound bar. And to vastly increase the audio coming from a sound bar, you need a subwoofer.
Done and done. For a limited time, and while supplies last, Groupon has the refurbished Vizio SB4021E-B0C 2.1-channel sound bar for $89.99 shipped. It lists for around $180 and rarely sells new for less than $160.
As you can see in the photo, this isn't just the typical elongated brick -- Vizio lent this a tapered, shapely design. I'm not saying it's gorgeous, merely that it's not as ugly as other sound bars I've seen.
As for the cube-shaped subwoofer, you can stick that out of sight. It's wireless, which is awesome, and it'll round out the sound in a way no sound-bar alone can.
Other noteworthy specs: digital and analog inputs, and Groupon even throws in a six-foot digital optical cable so you can hook it right to your TV, right out of the box.
Issues? CNET hasn't reviewed this model, and over at Amazon it earned about 3.5 stars from a few dozen buyers. The main gripe appears to be with the overall quality of the subwoofer, but, again, so long as it works, it should deliver a much better audio experience than you're getting from your TV's built-in speakers.
The only thing that gives me pause is the 30-day warranty. If you can, pay with a credit card that doubles the warranty on purchases like this.
Bonus deal: Need a new mouse? Or how about a spare? Today only, and while supplies last, Best Buy has the HP x3000 wireless optical mouse for $7.99 shipped (plus tax). Powered by a single AA battery, the mouse connects via an included USB receiver that barely protrudes from the port, so you can leave it plugged in full-time. User ratings: 4.5 stars (out of 5) from close to 600 customers. And I'm sure at least some of those were based on the regular price ($24.99).
