The C-Notes do require quite a bit of soldering on the crossover. Look at Youtube videos if you are not sure what to do. It isn’t hard if you take your time and have the right solder and soldering iron. There are a couple of extra things you will need to order if you get the kit like wiring, speaker ternimal spades, damping material and binding post that will increase the cost. It is a great speaker and well worth the time and effort.
