(57) The subject of the invention is an acoustic speaker consisting of the enclosure and
speakers: woofer and wideband, characterised in that the enclosure consists of a set
of upper chambers (1) separated from each other by partitions and a set of lower chambers
(2) separated from each other by partitions, moreover the wideband speaker (7) with
the outlet of acoustic wave emission directed parallel to the floor is mounted in
the front upper chamber (1a), whereas the woofer (8) with the outlet of acoustic wave
emission directed vertically downwards is mounted in the lower chambers (2a) and (2b).
Each of the upper chambers is connected to the chamber located below it by a waveguide
(4) made of a hollow pipe, whereby the front waveguide (4a) is closed from the bottom
a separate space creating with the chamber (1 a), and the remaining waveguides are
open from both sides, creating with the following chambers a low-pass acoustic filter.
Sets of upper chambers (1) and lower chambers (2) are additionally connected by means
of bars (5) and (6) pressing and tightening the whole enclosure, whereby bars (5)
are at the same time a metallic conductive connection between the wideband speaker
(7) and feeder clamps coming out in the set of lower chambers (2), whereas the bars
(6) provide support and stiffening for the whole structure.
