For 2nd order butterworth, Linkwitz-Riley, and bessel circuits, the values of C and L are always the same for the high-pass and low-pass by calculations. However, these C and L values for hi and low-pass are always different in a crossover which sold by the market.

Would someone tell me why?

The calculations for the crossover which give equal L and C are based on the assumption of a resistive load. In practice, speaker drive unit loads are not a pure resistance but have reactive components as well. The values of L and C are therefore adjusted to give a flat response with the particular drive units being used.
