The amount of power required for an application is primarily dependent upon the sensitivity of the speaker, the volume of the room and the desired SPL's. The speaker position is largely irrelevant to calculating the power requirements in a home application.

Certainly for sound quality and voice intelligibility, speaker positioning is extremely important. As well as for subwoofer positioning.

With regard to SPL, the greatest variations in the listening area of a room will be in the low bass frequencies which most in-wall speakers don't produce anyway. Furthermore, those variations, which can often be as much as 15 dB throughout room have nothing to do with whether the subwoofer is near ear level per se or not and are dependent upon room modes. Having more power would not affect room modes, which are the biggest factor in SLP variations throughout the room.
