Preface
Fig.1 – The multi-frequency active crossover
The project offers an universal solution that allows you to find and set the best cutoff frequency for an audio system’s subwoofer with no special equipment. Beyond this, in my opinion, practical listening is the best way to compare audio configurations and devices: charts, parameters and calcs are very important but they may not be respected when put into practice.
This crossover gives you the possibility to set six different cutoff frequencies: 63Hz, 80Hz, 100Hz, 125Hz, 160Hz and 200Hz. The right selection is the one that will make your audio system sound better.
