This is a quality crossover . the only thing I wished it was a rheostat type , instead of just a 2 position switch . Actually it is 4 positions total , due to it having 2 switches / one for mid-range and the other for treble . Still no complaints here !!! Shipping time was outstanding too !!! Using in one of my cars / special build using Electromavin's Fine speakers and crossovers . Buy one and receive two / my favorite deal / Ha Ha / I guarantee you will not be disappointed ...
