My center channel is a pair of Martin Logan Purity speakers. I split my center channel signal and sent it to both speakers. I built a stand and laid both speakers on their side top to top. This makes my center channel 102" wide and it sounds amazing! My front main speakers are a pair of Martin Logan CLS iiZ speakers with a REL T3 subwoofer tied in with each one to polish off the low ends. My side speakers are a pair of Martin Logan Source speakers. My rear speakers are a set of KEF Reference series speakers. My couch is set on a stand behind my recliners and the KEF's are on a stand to put them just above the couch. My LFE is a SVS PB13 Ultra and it will defiantly rattle the windows in the house. I have a 65 Mitsubishi Diamond 3D TV but am looking to upgrade to a 110” screen and projector in the next year or so. I have an Oppo 3D blue ray player, Xbox 360, PS3 and a Denon receiver driving things. I just got all the speakers done and will be adding amps later this year.
