Low-pass filters … WebThere are three basic ways to “crossover” or divide frequencies. High-Pass Filter: allows frequencies above the chosen cut off frequency to pass through to a speaker or group of speakers. Low-Pass Filter: allows for frequencies below the chosen cut off frequency to pass through to a speaker or group of speakers. WebAn ideal low pass filter is one that passes all low frequencies – below the cutoff frequency – with unchanged amplitude and one that completely stops all high frequencies.
