Have also still each have a 3cm thick marble top (granite tuts) under each subwoofer packed, as I have laminate flooring and thanks to the really big Subs otherwise the sofa crazy ;-)!
Jetz for sound, have the system on an Onkyo TX No run 929 THX, of course, only once calibrated everything and really used all eight measuring points, makes real from what!
BluRay player device is a PS4, the first directly Ironman I smashed right at the beginning when he is traveling in the convoy and was attacked, you felt sitting in the passenger seat, the explosion shook the whole living room (hence the 3cm plates ;-)) and still you can hear every stone trickle down.
Otherwise, I hear a lot of film music and soundtracks, and what can I say, I hear tones and subtleties which spared me before!
previously had a BOSE ACOUSTIMASS 10 with additional second Acoustimass module which already sounds great, but this is amazing, so full 5 stars! I can only recommend! Of course, an ordinary AVR from the 900 class
With CA 160W advantage!
