the reason a sine is used is that you can pick your frequency to match the original kick (say 50hz) and absolutly no harmonics or additional musical information is added whatsoever.
... meaning that there is absolutly no need to eq it.
(the reason eq doesnt work is because it is only one frequency - you could find the exact frequency and then eq will work but its pointless as all you could do is make the signal louder or quieter).
