NettetCrossover¶. Crossovers "split" the frequency band to send to different drivers. In a two-way loudspeaker, for example, a low pass filter is used to remove high frequencies from the signal sent to the woofer, and a high pass filter is used to remove low frequencies from the signal sent to the tweeter.. When integrating a subwoofer, high pass filters are …

NettetTo create a Linkwitz-Riley filter type using a real time audio analyzer like Smaart, you’ll need to figure out some way to measure a filter. If you have access to an output processor or a mix console with LR filter options, then set up a transfer function measurement with a loopback cable as the REF and the processor output as the MIC input. NettetLinkwitz-Riley filters are widely used in audio crossovers that have two outputs, a low-pass and a high-pass, such that their sum is equivalent to an all-pass filter with a flat magnitude frequency response. The Linkwitz-Riley filters available in this class are designed to have a -24 dB/octave slope (LR 4th order).
