Try it both ways to see which way you like it the best, but do not make quick decissions. Let it settle in for a while. If one tap or the other has never been used it may take a while for it to break in.
4 ohm or 8 ohm tap
I have a pair of AZ Adagios, they are 6 ohm speakers. Should I use the 4 or 8 ohm taps on my tube monoblocks?
