As posted earlier, do not believe everything you read on the internet, for example crossover settings and speaker break ins. Yes new speakers need to be properly broken in, contact the vendor, for example Elac had me break in my 5.2.4 setup by playing the speakers at full range with an 80% volume cutoff for 30-40 hours. After that I set the crossovers to 10hz above their spec. For example, my multieq app reads my towers, center, at 40 hz but I set them to 60hz based off of vendor feedback and my own experience. My atmos speakers measure at 250hz but I set them at 200hz based on vendor feedback and speaker specs. The goal is to have a matching crossover for all soundstage speakers and all effect speakers but obviously the Elac ceiling speakers can go much lower than 200hz so I have them set at 100hz based on vendor feedback and specs. Again, set the crossover to 10hz above spec, even if it means going lower than what you’re mic and software detects.
