Claims (5)

1. Højttalerkabinet (1), som omfatter mindst to kanaler (2, 3, 4), i hvilket en første (2) og en anden (3) kanal er bestemt til henholdsvis et første og andet adskilt og tilgrænsende frekvensbånd, hvor enhver af disse kanaler (2, 3) indeholder et filtreringstrin, der forsynes ved hjælp af styresignalet (6) og en højttaler (20, 30, 40), hvor højttalerkabinettet desuden omfatter midler (10) til på samme tid at frakoble den første kanal (2) af styresignalet (6) og modificere filtreringstrinnet (34, 37) af den anden kanal for at modificere frekvenskarakteristikken deraf ved at forskyde grænsefrekvensen af den anden kanal (3) i retning af det frekvensbånd, der er bestemt til den første kanal (2), kendetegnet ved, at frekvensbåndet af den anden kanal (3) er større end frekvensbåndet af den første kanal (2).
2. Højttalerkabinet ifølge krav 1, kendetegnet ved, at modificeringen af frekvenskarakteristikken omfatter en modificering af den tonale balance på hele eller en del af båndbredden.
3. Højttalerkabinet ifølge krav 1, kendetegnet ved, at filtreringstrinnet (37) af den anden kanal (3) omfatter et højpasfilter med en lav grænsefrekvens F0ff og ved, at det modificerede filtreringstrin (34) af den anden kanal (3) omfatter et højpasfilter (35) med en lav grænsefrekvens Fon, der er mindre end F0ff-
4. Højttalerkabinet ifølge krav 1, kendetegnet ved, at det modificerede filtreringstrin (37) af den anden kanal (3) omfatter en filtrering med en konstant dæmpning (36) ved en frekvens FLs, der er mindre en Fon-
5. Højttalerkabinet ifølge krav 1, kendetegnet ved, at den anden kanal (3) omfatter to filtrereringskredsløb (34, 37), der ved indgangen forsynes ved hjælp af det samme signal, og hvis udgange forbindes skiftevis til højttaleren (30) ifølge tilstanden af en omskifter (10).
