The directivity of current public address systems can be ensured in mid and high audio frequencies, using arrays and horns. Low frequencies however are often omni-directional. The cardioid subwoofer is introducing itself but has some drawbacks limiting the maximum sound pressure level achievable. As an alternative, the end-fire line array is considered a directive bass system. Previous research already done on end-fire arrays could not rely on our current digital signal processing techniques' potentials since non-existing at the time. Using a digitally processed end-fire array, the possibilities and limitations of these tapered end-fire arrays were examined to create a constant directivity end-fire array with a usable frequency range from 20Hz to 200Hz.
