Description
Here we have :
1 pair vintage full range speaker .
Made by RFT in early 1950 , made in East-Germany on old Lorenz and Körting machines
20 cm size = 8 "
tested, both are working properly , high efficient
natural sounding !
matched pair !
field coils and voice coil impedances are matched !
the values are equal
4.0/4.0 Ohm DC impedance , 4 ohm nominal
tested by Monodyn lab.
tested with 100 Volt DC source and around 80mA amperage
impedance of the fieldcoils are 1.6kOhm and 1.6kOhm -matched !
the baskets are bakelit made so no interference with magnet field of the basket .
One basket has a minor crack but not trough, see last picture FYI only.
The auction is for both speakers, perfect for single ended tube amplifer , very high efficient !
natural sounding
