An impedance peak of 13 ohms isn't terribly high, and is expected from a horn. There will be a few peaks near the flare frequency and its harmonics. There are also sometimes peaks caused by diaphragm mechanical resonance below the flare frequency, where the horn cannot load the diaphragm. To tame these peaks, and electrically mnatch the driver better with the crossover, I suggest you use a shunt resistor damper. Please see the π Crossover Document for more information.
