Logitech seems to be the first brand of speakers that will come up to your mind if you’re looking for a speaker for your computer, or even for your home theater, right? Well, simply because the brand has been here for ages and has been offering speakers and all manner of other computer gears for a long time. By the way, their latest is - the Logitech Speaker System Z623, a 2.1 speaker system for computer users that’s THX Certified meaning that it has had more than 400 tests performed to cover frequency response, power and more. The system has all the controls that you need, for volume and for that chest-thumping bass on the right satellite speaker. It has 3.5mm jacks, RCA ports, and a headphone port for private listening. The Z623 can also be connected to several sources at once including your TV and PC. $150.
