ABSTRACT OF THE DISCLOSURE A bass reflex enclosure or cabinet of the kind in which a loudspeaker unit is mounted in an opening of a front plate and at the end of two coaxially mounted tubular members extending into the interior of the cabinet so that an annular slot is provided around the speaker unit and, in a known manner, utilized as a bass reflex port arranged coaxially with the speaker unit. The speaker unit is fixedly mounted on one end of the inner tubular member whereas the outer tubular member is fixedly mounted to the front plate or forms an integral part therewith. An assembly comprising the inner tubular member having the speaker unit mounted thereto is suspended from the front plate by means of a number of vibration absorbing rubber blocks which are evenly distributed around the periphery of the speaker. Thereby an acoustically dead front plate is achieved.
