I might have missed it, but a better way to look at the Large v. Small issue is not one of size, rather Bass Management On or Off. (I think the large and small description is foolish.)\nWith that “small” speaker compensation issue ;) out of the way, and some good subwoofers in place, you are just working on managing the Bass distribution between speaker and sub. :)\nHow do you decide if you have speakers capable of running Full Range? If the FR is -3dB at 20Hz or lower, than you have Full Range speakers. (Maybe an F3 of 25Hz is ok too... just depends on your listening choices and habits (loud Electronica or HT? I would engage Bass Management and still send that programming to the Sub.)\n\nPlease follow up with how you like everything once you get it all in place!\n\nCheers!
