Bandpass vs. Resonance
An LC filter is superior to using RC low and high pass filters for several reasons.  One, it will provide a 12 dB/octave rolloff on both sides of the desired frequency while a single RC filter can only provide a 6 dB/octave rolloff.  Two, it will automatically provide a symmetrical response around its center frequency while the 2 RC filters must have matching components to achieve this.  Three, the Q of an LC bandpass filter, if a good quality inductor is used, will exceed that possible with RC filters. However, LC filters can be physically large depending on the frequency. Also inductors are subject to non-linear effects if the signal levels are large.
