Have you tried the AVR with any other speakers to make sure it is working properly?\nYou said it was your dad's old AVR, so I am wondering that there might be something off about it.\nAlso check the manual and if there is a "reset" option, I would reset it just to make sure there are not any errant settings lurking! If not, put it in "Stereo Direct" mode\nAlso make sure that (assuming you are feeding it from the TV) you go through the TV menu and disable any "audio enhancement" "features". The idea is to get everything back to the "plain-Jane" signal, then you can play with any tweaking from there. For example, a EQ system to help the TV speakers may artificially add bass and treble to help out, but with good speakers like the Infinity R162's you don't want that.\nIs your source the TV? How is it connected to the AVR?\nAs you describe it, I think the issue is something bigger than position of your speakers. These speakers with the R12 should far exceed a Vizio soundbar (although I do believe Vizio makes some decent soundbars - but they are limited to typically 3" drivers and often the sub is more woofer than subwoofer!\n\nYes, good idea. Before you give up on the speakers make sure the issue isn't with that receiver!\n\nQuick story about a personal experience had when I upgraded my subwoofers. I went from budget 10" subs to higher quality 15" subs and was thoroughly unimpressed at first. My little 10" subs seemed to play louder than the 15s! Wtf?? Well, as it turns out my new subs seemed quieter because the distortion was gone! I wasn't used to hearing really tight clean bass. It took me some time to readjust my expectations.
