Etymology
鈍 combines 金 (metal) with 屯, which likely contributes the sound and suggests something thick or blunt. The idea is metal that is not sharp.
Meaning mnemonic
Metal 金 that is thick and blunt 屯: a dull blade that cuts slowly, if at all.
Reading mnemonic
For ドン, imagine a dull blade that goes 'don' with a heavy, slow thud instead of slicing cleanly: don -> ドン.
