How Do You Spell DUNNESS?
Pronunciation: [dˈʌnnəs] (IPA) 
The spelling of the word "dunness" is a bit tricky. It is spelled with a double "n" which might suggest that the "u" is pronounced like the "u" in "sun". However, the implication of the double "n" is actually to indicate that the preceding consonant should be pronounced with extra emphasis. Therefore, the correct pronunciation of "dunness" is /ˈdʌnnəs/, with a short "u" sound as in "hut" and emphasis on the "n" sound.
