The Logitech Z-5500 5.1 speaker system features a total of 505 watts, four satellite speakers, a center speaker, a subwoofer, and a Digital SoundTouch control center. Each of the system's satellite speakers has an output of 62 watts, the center speaker has an output of 69 watts, and the large subwoofer has an output of 188 watts. Similar to other Logitech systems, the satellite speakers feature removable cloth grilles, rotating pedestals, and are able to be wall mounted. The control center had audio decoders that support Dolby Digital, DTS, DTS 96/24, and Dolby Pro Logic and is THX certified. The Z-550's analog and digital audio capability allows the unit to connect to PCs, DVD players, CD players, game consoles, and portable digital music players. Connectivity options include coaxial and optical digital inputs, a headphone jack, and a wireless remote. Performance wise, the Z-5500 is similar to the Z-680, but it features a redesigned control center with a better knob and an easier-to- read display. Also similar to the Z-680, Z-5500's center speaker emits a barely audible hiss when there is no sound playing. Also, when compared to other 5.1 speaker systems, the Z-5500 is a bit expensive. Overall the Logitech Z-5500 is best suited for users who want a versatile home speaker system with an array of connectivity options and audio decoders.
