Crossover

 
Added by DIYMA, 03-28-2012 09:35 PM
A frequency divider. Crossovers are used in speakers to route the various frequency ranges to the appropriate drivers. Additionally, many crossovers contain various filters to stabilize the impedance load of the speaker and/or shape the frequency response. Some crossovers contain levels controls to attenuate various parts of the signal.Â*A passive crossover uses capacitors, coils, and resistors, usually at speaker level. A passive crossover is load dependent (the transition may not be very smooth or accurate if a different speaker is substituted for the one the crossover was designed for). An active crossover is based on integrated circuits (ICs), discreet transistors or tubes. An active crossover is impedance buffered and gives a consistent and accurate transition regardless of load.
