Nope, just a couple of resistors. Nice part is that you can hang it all on the back of the tweeter, so you don't need to open the cabinet or trace out the crossover. By the way, it's called an L-pad because the two resistors form an L. There are also T pads; but you don't need one of those.
The rotary control we call an L-pad is really a variable L-pad and as you rotate the shaft, it changes the series and parallel resistance to maintain a constant input impedance.
