Subwoofer guys - House curve or flat?


So there's a bit of debate about whether a "house curve" should be used instead of EQing your sub for a perfectly flat response. My thoughts are adding a house curve could possibly muddy up the midrange and I like it how I have set up now (perfectly flat) Is this true? Anyone do any experimenting?

Here's a lot of information from the home theater guys on why you should "shelf" response.

Duke said, "In my opinion what you want is flattest possible in-room bass without causing problems......... Note that once boundary reinforcement and modal effects are factored in, what may have started out as "flat" response is now far from it."

How would we know this? Is there any way to measure this?
If this is true what can be done to change it?
