What is a Butterworth crossover?
It is also known as a Butterworth squared filter. A Linkwitz–Riley “L-R” crossover consists of a parallel combination of a low-pass and a high-pass L-R filter. The filters are usually designed by cascading two Butterworth filters, each of which has −3 dB gain at the cut-off frequency.
What is a 4th order crossover?
4th-order Linear-Phase: (A seldom used filter that is constructed with an asymmetrical filter topology.) Produces a -6 dB crossover point to achieve a nearly flat amplitude response with moderate ripple. The summed group delay produces a moderate bump just below the crossover frequency.
What is LR24?
The LR24 is a mid-size line-array sound system, designed to enable a 1:1 non-compressed reproduction of the original sound source at any sound pressure level; Due to the completely neutral response of the system, it can be used for any application and source possible, from speech, to classical music, jazz, all the way …
What is a Linkwitz transform?
A Linkwitz transform is a mathematical operation that changes the effective F and Q to different values. Typically, this is used to lower F to get more low bass output, or to lower the Q to make the box behave like a larger box.

What is a high pass crossover?
High-Pass Crossover A high pass crossover allows high frequency signals in the 5kHz-20kHz range (generally) to be passed to the speaker/tweeter while the lower frequency signal is blocked.
What are crossover frequencies?
The crossover frequency is the frequency at which sound transitions from one speaker to another. In a passive speaker, the electronic crossover components determine where the sound transitions from the speaker channels to a subwoofer. The crossover frequency can also be set manually if further optimization is needed.
How do I make my crossover active?
How to Operate Active Audio Crossover Circuit? Provide +15V and -15V supply to the active crossover circuit from Dual power supply circuit. Apply the audio input to the circuit with the help of audio jack. Switch off the supply.
What’s the difference between Linkwitz Riley and Butterworth crossover?
Each of the filters has a different Q value, which give different amplitude responses. BW is Q or 0.49, LR is 0.71 (which is 0.49^2), which is because it’s just a double BW filter. LR filters are -6 dB at crossover, so they sum to flat (0 dB). BW are -3 dB, so they sum to +3 dB. Click to expand… Great link. Thank you Bill.
Who is the author of the Linkwitz Riley crossover?
In 1976, Siegfried Linkwitz published his famous paper [ 1] on active crossovers for non-coincident drivers. In it, he credited Russ Riley (a co-worker and friend) with contributing the idea that cascaded Butterworth filters met all Linkwitz’s crossover requirements. Their efforts became known as the Linkwitz-Riley (LR) crossover alignment.
What’s the difference between Bessel and Butterworth crossover?
Bessel filters are for keeping an even phase/group delay. Each of the filters has a different Q value, which give different amplitude responses. BW is Q or 0.49, LR is 0.71 (which is 0.49^2), which is because it’s just a double BW filter. LR filters are -6 dB at crossover, so they sum to flat (0 dB).
What is the magnitude response of the Linkwitz-Riley filter?
Comparison of the magnitude response of the summed Butterworth and Linkwitz–Riley crossover filters. The Butterworth crossovers have a +3dB peak at the crossover frequency, whereas the L-R filters have a flat summed output.
