Downfire bass reflex: Denotes a design of subwoofers and a few floor-standing loudspeakers (so-called omnipolar). At the same time, it shines Chassis down towards the ground. speak the Membran sits under that Subwoofer, not visible, aimed at the ground. The reason for this design has purely cosmetic reasons, since the wavelengths in this frequency range (e.g. 120 Hz at a wavelength of 1,2 m) are so large that the direction of radiation has virtually no decisive influence.
