I got the massive Logitech z 906 last December 2017.My movies watching experience with these speakers is just awesome.It is THX certified DTS Digital surround and awesome experience be it for movies or music comes with 2 years warranty too.It has an output of 500 Watts RMS. It is remotely controlled where one can select the effect of it is 2.1 or 4.1 or 5.1. One can also mute it anything that is on the computer be it music or movies. The remote comes with two 3 AAA batteries from Duracell, instructions manual is also included in the box. The box is safely packed with good cardboards easy to open no need for expert advise from any sound engineers of any sort. I kept all the speakers on my desktop table itself so the sound is a booming effect. The criterions sound exactly as seen in movie halls.
