What is the difference between Linkwitz-Riley and Butterworth?
A Linkwitz-Riley filter is made by combining two Butterworth filters. The main difference between the two is that Butterworth crossovers are 3dB down at the filter cutoff frequency while the Linkwitz-Riley filters are flat.
Does an active crossover need power?
Active crossovers always require the use of power amplifiers for each output band. Thus a 2-way active crossover needs two amplifiers—one for the woofer and one for the tweeter.
What is active crossover used for?
Active crossover operating at low signal levels. Audio electronic crossovers allow to split the audio signal into separate frequency bands that can be separately routed to individual power amplifiers which then are connected to specific transducers optimized for a particular frequency band.
What is 4th order crossover?
An electric 4th order crossover is four components per driver and is designed to achieve a 24dB/Octave cutoff. Since most speaker drivers are designed (or incidentally limited) to have a cutoff at the end of their desirable operational bandwidth, a proper crossover design incorporates that cutoff.
