Unless the filter was very steep, it would not do much good - it would either affect frequencies well above 30 Hz, or mostly affect frequencies where there isn't much signal in your average recording. Making a very steep passive filter is very tricky, and you would probably end up burning the same amount of power anyway, just that it would heat the filter instead of the speaker voice coil.
