Evo mozda je ovo totalno banalno pitanje ali isto me zanima da nebi nesto sje*a...
Iman par 2" full range zvucinka(5W RMS) i tija bi ih spojiti umisto visokotonaca da ih isproban, sad me zanima jel ja njih mogu spojiti normalno priko skretnice bez da ista zaseren posto su mi visokotonci 4 Ohm a full range je 8 Ohma???

da se nadovežem
u slučaju različitih otpora drivera i skretnice, koje područje je jeftinije ili lakše promjeniti ???
npr. midbas od 6 Oma na skretnici od 4 Ohm sistema s njegovim visokim ...

Visoko bi trebalo biti jeftinije (manje zavojnice i kondići)

ovisno o tome kojeg reda je skretnica i koja je rezna frekva.
no rekao bih da ti je jeftinije preračunavati i preradit visokotonski dio , znači raditi highpass filter nego lowpass.
primjerice, u šrotex varijanti možeš staviti bipolarca , tipa neku rauh foliju koja košta par kuna, dok bi za neku zavojnicu ubio 20ak kn...

ako se stavlja driver većeg otpora od postojećeg na skretnici,  dali se rez smanjuje ili povećava ?

pada.

primjera radi,
Impedancija zvučnika : 4Ohm
Kapacitet : 10uF
rezna frekva cca 4kHz

Impedancija zvučnika 8Ohm
isti kapacitet
rezna frekva cca 2kHz

govorim o highpass filteru prvog reda.

a za lpf? Znači skretnica je nekih 3kHz. Sa 4ohma driverima, a stavlja se mid od 6ohma, rez od 3hz bi bio ok, al bolje bi bilo višlje.

zaboravih odgovorit, sorry

za lpf prvog reda (6dB po oktavi) na 4 kHz ti treba 0,24 mH zavojnica..ako je driver 6Ohmski
za 3kHz bi trebalo 0,32mH no nekakve standardnije verzije su 0,30 ili 0,35 mH
