I mean the driver from 14Hz to 150HZ gas absolutely linear impedance as it has no active load. I look at all of it and felt so tiered and I walked out if it. I think in the new room the horn is shooting into the wide open sealing and see no reflection  and all my back chamber calculation and testing the worked so great for horns in basemen is absolutely not applicable now.
Romy , if your driver behaves like resistor - it seems like something stopping it . If the motor cannot move , we'll see only active resistance of the coil - exactly what you see . Maybe your foam in the back chamber expanded in some way , and blocked the speaker cone .
