I actually own a set of Logitech Z-5300s and let me tell you, some of the best speakers I've ever heard. I work as an Audio-Visual Technician and a musician so I think it is safe to say I am an audiophile and I've yet to hear computer speakers with better range and sound quality. There are obviously 5 satellite speakers in this system each with a 2.5" mid-range driver and a 1" titanium(I think) tweeter in the center. Each satellite also has two air ports in them for better quality and decrease in distortion. The subwoofer is a monsterous twin chamber 10" driver, actually it might be 8". But still one part of it is sealed so that the bass sustains and then there is a ported section to increase the hit of the bass (the port is 6" in diameter); it pretty much has the best of both worlds on the bass side, which reminds me the sub has and amplyfier on the back of it. I believe its 550 Watts and 625 peak so that is some power behind those drivers. It comes complete with a wired remote which adjusts volume, bass level, center level, and fade. It also toggles the sound matrix mode, which makes very negligible differance. There are alot of wires but that comes with the territory of a 5.1 set up. In real life testing with the speakers at 3 ticks (each "tick"= 1 LED light) and my laptop's volume at 40 it more than fills my room with full sound. When really cranking it up (I've owned these for over a year and have never gone to full volume on system and PC for fear of knocking a wall down/breaking a window) to about half volume on the speakers control and full on my PC you can hear them clearly two floors up. Hope that helps you out.
