I want to attenuate my 4ohm tweeter by 6db.
The resistor values I need, according to a calculator, are 2r (series) and 4r (parallel), both 10w, but I can't find the exact values. The most approximate ones I can get are 2R2 and 3R9.
What are the problems of using these values instead?
Will it change my 2nd order passive hpf cutoff frequency a lot?
Will it impact my zobel network?
The plan is to connect: amp->hpf->lpad->zobel->tweeter
Thanks in advance

You can model this up very easily in Xsim, and see the predicted differences in frequency response for yourself. If you don't use Xsim, you should try it. It's very simple to use, effective as a crossover modeling tool, the author is on here, and it's free. These days I use it more often than a significantly-not-free crossover software I own.

The resistors are fine, and are more accurate than the tweeter's value.
