oneday, I found planar headphone and planar tweeter have same operation method.
It gave me inspiration and convince me that can use to headphone.
So, I am searching some planar tweeter in taobao.
It's price is only 20~ 35$ for each unit, I think this price is very cheap.
unit : hivi rt1.3
measurement system : panasonic wm61a (I using BMF's circuit)
housing : rosewood and finished by shellac
hairband : hifiman fake
housing assembly 1
housing assembly 2
housing assembly 3
my soundcard is ALC892 so I couldn't mesure it exactly under 150Hz and over 17khz.
I can find little difference comapre left with right because diaghram was stabbed when I assembled it.
total is about 170$ because I almost used 70$ to housing
if you use plastic housing, you can make it about 100~120$
I'm not good at English so if you find out some error in writing, please point out it
