Can anyone out there give me a clear cut answer on what this setting does? I have asked before about how to set up my current speakers for 7.1 theater. I have paradigm monitor 11's for fronts with cc370 center and 6.5" in ceiling and inwalls for t=my surrounds. My sub is the paradigm pw2200. People tell me to set all speakers to small with sub @ 80-100hz. However recently I was told by a sales guy at a local high end audio/ video store that those monitor 11's should be set as large with the sub setting to PLUS. My receiver is a Pioneer elite txi55 and gives you three options for sub setting. (1) No, (2) Yes, and (3) Plus. If you select plus what would you now set for the crossover? Still leave it at 80hz? The manual for Pioneer gives nothing for this setting. Please help if you know or have opinion. I'm currently happy with the small setting, but now its got me thinking. Which can be dangerous!
