Not sure if I understand your question, but what your describing is happenings is exactly what is supposed to happen. There's no way a kick drum at two different frequencies would have the same "power". There are two factors you need to consider:
1. different frequencies have different "power" so if you put a kick at 60hz its going to have a lot of bass and sound boomy, but if you put it at 130hz it will sound punchier
2. most rooms have certain resonant frequencies (when the length of the sound wave or a multiple of the sound wave exactly matches the length of your room) when a note is played at this frequency, it will sound louder than it really is, because the sound is being amplified or attenuated by your room. Try listening to your mix in headphones or on a different set of speakers in a different room to see if it sounds different.
hope this helps.
