Band Pass Filter Equivalent Components
In your first circuit, the high-pass filter (analysed on its own) has an output impedance not greater than 3 ohm (R1 dictates this). Your low-pass stage has an input impedance not less than 35 ohm (R2 dictates this) and, when looked-at together you can see that the low-pass filter stage is applying very little loading to the high-pass stage and you roughly get what you expected.

In your 2nd circuit with R1 = R2 = 10 kohm the 2nd stage is much more heavily loading the first stage and this screws up the nice response as seen in the first circuit.

If you want to use a simple RLC pass band filter you need to describe what bandwidth you need - it might be that what you want in terms of bandwidth might not be realizable from a simple RLC circuit and you may need to cascade two - then you are back to loading problems.

The best choice is made when you decide what you want in terms of bandwidth and out-of-band rejection characteristics.
