AmazonOne of the best ways to improve your computer setup without opening it up is buying some good speakers. 

Music and movies will sound better than the smaller speakers that come bundled in with your computer.

It's not their fault they sound smaller and more tinny — it's physics.

Logitech's 2.1 system can be used with your computer, but they're also powerful enough to work as an inexpensive home theater system.

The speakers themselves are pretty standard: two small bookshelf-style speakers with a square subwoofer. But, at 200 watts of power and a THX certification, they're going to sound loud and clear regardless of what you're watching or listening to.

When buying a speaker set, something I look for is how I can connect my gadgets to it, and how many can be connected at once. These speakers have a standard 3.5mm audio input for your computer, and auxiliary ports so you can connect two additional devices.

These speakers also have my favorite computer speaker feature: a headphone jack on one of the speakers. If you keep your laptop docked, or your desktop in a place where it's hard for headphones to reach, this is a major win. 

People who have used these speakers seem very happy with their sound, especially for movies. With music, most people are happy, but some have reported a little extra top end and weaker midrange, something to keep in mind depending on what you listen to.

A lot of people also praised the power they could get from these speakers. "Room-shaking" one person called them. So, if you're looking for speakers with oomph, there's no lack of it here. That's encouraging, because if you decide to use these speakers, chances are high you'll be sitting further away than you would sit from your computer. 

It's not going to best a high-end audio system, but for the price, these speakers are capable of producing better sound than your built-in computer speakers. They're also built for TV use, so if you're looking for a budget-friendly way to improve your home theater this is an option for you.
