:rolleyes: Salut all, am revenit si yo cu o intrebare.Am vazut pe forumuri audio in special pt auto ca unii au subwoofere cu doua difuzoare...ma rog si cica au 4 ohm fiecare difuzor si ca daca le legi in paralel faci 2 ohm :smt012 .Am desenat si o schema asa cum cred eu ca ar fi paralel(defapt asa inseamna paralel din ce am facut la fizica parca), dar pana la urma cum da din 4 in 2 ohm :smt006 PS: nu stiu daca ati inteles ceva dar incercati sa ma lamuriti si pe mine.Unele chestii sunt limbii straine pt mine dar a inceput sa ma pasioneze si...vreau sa aflut cat mai multe :supz:

Legarea e corecta.Din punct de vedere fizic treaba sta cam asa: 1/Z1 + 1/Z2=1/ZPZ1, Z2: impedantele celor 2 difuzaoreZp impedanta la legarea in paralelaceasta regula este valabila si la mai multe difuzaore puse in paralele:1/Z1 + 1/Z2 +...+1/Zn=1/ZPde ex pt 3 difuzoare cu impedanta de 8 ohmi elgate in paralel veia vea o impedanta de 2.66 ohmi, iar pt 2 de 2 ohmi.In serie treaba sta la modul urmator:Z1 + Z2 +...+ Zn=ZS
