Re: Impedance question on double 15 with a hornThere's also the issue of combing caused in double 15 boxes where the 15s go up to high and uncouple due to the shorter wavelengths of the mids. I know JBL on some of their double 15 + horn boxes put a low pass filter on the second 15 to roll them off at a lower frequency to avoid that issue. So unless you're horn is solid down to 400-500Hz, and you low pass your dual 15s there, you're going to have some issues.
