Hi, I recently purchased some a pair of R-28F, I am planning on connecting them as Bi-Amp. I read they are supposed to be 8Ohms, but decided to meassure them with my multimeter. I meassure 4-4.2 ohms on the terminals, is that correct? If I remove the "bridge" and meassure the bottomn terminals, I get the same, if I meassure the top (tweeter?) I get nothing. I am not an expert on this, but should I not be meassuring 8 Ohm here?
