The aim of the research paper is to design a crossover circuit for loudspeaker that will be used with a 2-way speaker. Circuit consists of the resistors, capacitors and operational amplifiers connected in the filter. Linkwitz riley filter satisfy most of the conditions for smooth response of the speakers. It consists of active filters which provide better function and efficiency than the passive filters because of presence of operational amplifier. Passive filters are not used due to the presence of inductors which creates certain problems. In Linkwitz Riley filter, high pass and low pass filter are connected in parallel. Value of all resistors is 23.7 k? and that of all capacitors = 68 nF. Series notch filter is also used to correct the speaker impedance.
