What is dB and Octave in crossover?

Crossovers Slopes Crossover slopes are the amount of attenuation per octave from the crossover point in decibels. These attenuations are also referred by order of slope. An Octave is a doubling of frequency, from 50Hz to 100Hz would be considered one octave. 1st order: 6dB per octave. 2nd order: 12 dB per octave.

Which is better Butterworth or Linkwitz-Riley?

The Butterworth has the sharpest initial cutoff, and a +3 dB sum at crossover. The Linkwitz-Riley has moderate rolloff and a flat sum. The Bessel has the widest, most gradual crossover region, and a gentle dip in the summed response. All responses converge at frequencies far from the design frequency.

What is an LR2 crossover?

Second-order Linkwitz–Riley crossover (LR2, LR-2)

There is a 180° phase difference between the low-pass and high-pass output of the filter, which can be corrected by inverting one signal. In loudspeakers this is usually done by reversing the polarity of one driver if the crossover is passive.

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.
