Sound emitter on sub-woofer-satellite principle - has mono-bass boxes for left- and right-hand channels of sub-woofer

摘要

The subwoofer of the sound emitter utilises the principle of `box with defined aperture'. It does not have a common housing for the low bass radiation of both stereo channels such that separate monobass boxes are allocated to the left- and right-hand channel respectively. They can be located in radiator recesses, empty corners, under seats etc. Pref. the capacior, necessary for the trimming of locatable frequencies, is incorporated in the low pass with different dimensions from the standard and pref. 100% larger capacity value. For reducing the loudspeaker noise, the defined aperture in the rear box region is fitted behind the loudspeaker, or round the magnet. ADVANTAGE - Reduced loudspeaker own interference noise, and effective utilisation of stereo arrangement.
