Display apparatus (10) comprises a flat panel loudspeaker (12) and a visual display board (14) positioned in front of the flat panel loudspeaker (12). The loudspeaker (12) and visual display board (14) are retained in frame (20). Sound generated by the flat panel loudspeaker (12) may be heard by an observer (30) despite the disposition of the visual display board (14) therebetween. In this way, the observer (30) may view and hear complementary information from the display apparatus. The visual display board (14) may be removed readily from the display apparatus (10) and replaced by new visual display board showing different information, without having to dismantle any part of the flat panel loudspeaker (12).
