I am building a crossover between my soft dome tweeter and a ribbon / planer driver. The freq of the crossover is 10 KHz. The planer is listed as 8 ohms. The soft dome is listed as an 8 ohm impedence, whereas the DC resistance is listed as 5 ohms. Yes, I confirmed that. About 5.4. With both at 8 ohms logged in a crossover tool they both would require 1 uf capacitors, and .25 mh inductors for an LR 2nd order at 10 KHz. Question, I intend on padding down the soft dome a tad to make a more seamless crossover point. Would 2 additional ohms of resistance in series with the soft dome accomplish what I need? Asking as the DC resistance would then be just under 8 ohms. In the original design there was a 4 ohm resistor, with two more 4 ohm resistors, terminated, for tweaking if necessary. |
