Logitech Surround Sound Speakers Z506
This is basically the "budget" model of 5.1 speakers from Logitech, so keep that in mind as you look at them. The speakers are good, though with 75 watts RMS of power they’re certainly not nearly as powerful as the ones available in the Logitech Z906 setup; however, at 1/4 the price, that's to be expected.
There are multiple inputs on the subwoofer, so you can connect multiple devices to these speakers, but they don’t have a control center to easily switch between them. You also have to adjust volume directly on one of the satellites, so potentially restricts how you set them up; a simple control pod would be a great addition. The speakers are made from solid, quality materials and include metal mesh driver covers, giving you a solid overall system covered by a two-year warranty.
