Ventilated housing for bass loudspeaker has reflex channel divided into parallel sub-channels of different widths by longitudinal walls; sub-channels can be closed individually or in common both from the inside and the outside

摘要

The housing is a bass reflex box or a bandpass with a ventilation opening connected to a reflex channel with which the acoustic signal radiated from the back of the speaker into the housing can be fed out in altered form. The reflex channel is divided into parallel sub-channels of different widths by longitudinal walls. The sub-channels can be closed individually or in common both from the inside and the outside.
