- The 'Power Response' is irrelevant. You are not everywhere in the listening room, you are at a specific position, hopefully more or less in front of your speakers. Reflected waves are attenuated by the reflection surfaces, and walls in the US are semi-transparent to low frequencies. Moreover, a large part of the reflected sound is out-of-phase. The 'Power Response' matters only in a all-concrete small lab, and the response at the listener's hears would still be different.
- The floor is typically a very strong reflector of low frequencies (and sometimes of mids and highs also - wood, stone, tiles). When out-of-phase, the reflection attenuates the direct sound.

As you, I don't have the ceiling's reflection problem, but often it is less critical than the floor reflection, except when the speakers are tall, the floor above made of concrete and low.
