Akhil, We have had Likwitz as a guest speaker at our audio club. I am intimately familiar with his and his associate, Riley's, theories on crossovers I have an active crossover in which I can plug in a card which can be configured to any order. The Likwitz- Riley 2nd order is not to my liking. Jerry "A.
