Vented-box Geometry and Low Frequency Reproduction: The Aerodynamical Approach
To-day, low frequency reproduction with loudspeakers in vented box is limited by two factors: the volume of the box, and non-linear airflow through the vent. We propose a novel approach that takes into account aerodynamical parameters, leading to original profiles and an improved functioning of the vented box. For example, under certain alignment conditions, there exists a second cut-off frequency below the first one, localised on the lower impedance hump. Using this lower cut-off frequency and an adapted vent profile makes it possible to radiate frequencies around 40 Hz with box volumes smaller than 1 liter and small drivers. A prototype will be demonstrated.
