I have a relatively modest budget (1-1.5k) to buy a home theater setup and have been trying to make the most use of what I could, but I am stuck as to what receiver would make the most sense for me. Over black friday sale I bought a set of 7 speakers in Sony Core series (2xfloor standing @$100\/each, center @$100, bookshelf speakers $75\/pair, atmos up firing $100\/pair). I then spent $500 on a sub (pb12-nsd). For a receiver I went with the Denon AVRS740 ($350).\n\nThe room I am in is shaped like an L, with my setup facing the bottom _ of the L with the subwoofer in the corner (if that makes sense). I am sure I need to mess around in positioning the sub, but I am finding that either the volume of the whole setup is either too loud or not loud enough. Given the shape of the room, my listening position is fairly close to speakers (~8ft from front, ~5ft from rears, ~11ft from sub). I just can't seem to get the settings where I can clearly hear the full soundstage without it being uncomfortably loud and the bass booming\/shaking or too quiet to not get a full experience. Crossovers at 80hz, Front L\/R are full signal, subset to LFE+main. I have messed around with the various MultiEQ settings available on the S740. \n\nMy question is whether some of the difficulty I am having in getting everything setup could be solved with a different receiver (since I can't fix the room shape\/size)? The DenonX2400 is about the same cost had as the stepped up Audessy MultiEQ - but I just don't know how much of a difference the extra satellite filters will make (the sub filters are the same). \n\nAnyone have an idea on whether the MultiXT would make an appreciable difference or whether the X2400 would otherwise perform better over the S740? Alternatively, is it possible (at least for the sub issue) that I just bought too much sub and should switch to a sealed box instead (sb-12 maybe?).\n\nI am using this setup connected to PC and PS4 for both for video games\/movies but not really for music.\n\nThank you!
