Now have the Logitech Z906 recently are at my house. Why I have chosen for the Z906 and Z5500 or not for a system of vicious. Well I have the Z5500 already hanging as a sound system on the PC and performs there prima his service. In addition, the Z906 can completely operated directly with the included remote control from the sofa and also be switched which is not the case with the Z5500 (must be switched on only the back of the subwoofer). A next advantage is that the system may also like the Z5500 via a single cable (Optical) can be connected to an LCD TV, sound card etc. What struck me immediately is that the package is significantly smaller than that of the Z5500 which I had not really thought. When unpacking, I knew then why. The subwoofer of the Z906 is significantly smaller than that of the Z5500. When I then connected the system, of course I had the sound quality equal times test and compare my Z5500. It should be noted that the two systems do not give too much technically sound. Voices and music come clear over just as you would already know the Z5500. Only the subwoofer of the Z5500 appears to have a bit more power than the Z906. Is no wonder the sub. the Z5500 is also significantly larger and heavier. Nevertheless, the Z906 can build enormous bass pressure if far turn the knob clockwise. But to surpass to the Z5500 is not quite enough. Use my Z906 gaze to watch movies and listen to music, it was connected with NEM optical cable directly to my LCD. Finally, I must say that the Z906 is sonically pretty much identical to the Z5500, however, should be wenns louder, the Z5500 has a little more power. Nevertheless, the Z906 is recommended without hesitation because it has more than enough power and can also produce powerful bass. In addition, it can be turned on directly by remote control what I see as an advantage over the Z5500.
