I read HK's (525) document on how to avoid creating a frequecy gap between your sub and speakers. Here is a quote from it: "For example, if the setting for the front speakers is 80Hz, but the setting for the center or surround speakers is 120Hz, you must set the subwoofer to 120Hz, even if the front speakers have a better frequency range. A lower frequency setting for the subwoofer would create a bass “hole” because some frequencies would go to neither the subwoofer nor the main channel speaker, and thus be lost." Question: Using the settings above, will bass doubling occur on the main speakers between 80 & 120Hz? Of course it seems like this should not happen since it would make having variable cross over settings per speaker group pointless but you never know. Any HK 525 users about know this?
