I bought the newest headphones from Monoprice out of pure curiosity. They come with a four driver configuration on each side - one woofer and three tweeters. I took them apart and found out that the tweeters are actually come as a single block with two leads - hot and ground and the headphonee measure 32ohm.
I want to design a passive crossover for this headphone but don't know where to start. I made crossover circuits before for regular speakers and there's a ton of info on the subject all over the internet but when it comes to a crossover for headphones I don't even know what should be the crossover frequency in a two driver configuration so any help will be extremely appreciated.
