[Wayne A. Pflughaupt]

The movie industry has their own version of what a house curve should be, that suits their purposes.

For instance, they may be reducing below 63 Hz to minimize low frequency bleed-through to adjoining theaters.

Again, the X-curve discussion was only meant to show that house curves are necessary both in production and playback. The X-curve itself is of no use in a home theater, unless one happens to prefer sagging lows and highs.
