Hello!\n\nThis question gets asked A LOT, but I'd like a gut check as I'm reading so many conflicting things about crossover settings. In essence, should I set each of my channel pairs manually, or set the receiver to 80 Hz and be done with it? I do care about good sound, and don't mind setting things manually if I can make it better. Here's my system:\n\nSMALL SQUARE ROOM 15' x 20' DOLBY ATMOS 7.1.4\nMarantz AV8802a Receiver\nTwo Marantz MM8077 Amplifiers\nDefinitive Technology SubAmp 600\n\nIN-WALL SPEAKER SETUP\nL\/R DI 6.5 LCR (Recommended 40 Hz XO)\nCenter CS9080 (Recommended Full Range)\nSurround UIW RSS III (Recommended 120 Hz XO)\nRear Surround UIW RCS III (Recommended 60 Hz XO)\nHeight DI 6.5S Recommended 60 Hz XO)\nSubs 2X IW Sub 10\/10 (Range 16 Hz to 200 Hz)\n\nI'm asking the question for a couple reasons. First, the recommended XO for all the speakers vary wildly. I read that I shouldn't have XO settings with that large a range if I want a well integrated sound. Second, a frustration, my center channel says to use it full range because it has an 8" driver and a passive 10" radiator. But that receiver won't let me set the L\/R to small and the center to large. I'm not sure what to do about that or if I should care. Third, I'm using LFE, and not LFE+Main because that's a whole different topic.\n\nI know a LOT of this is subjective, but want some rules of thumb or best practices given this quirky system.\n\nThank you in advance!
