Nice,although not digging the Yellow paint.Its bound to affect the speaker,and its not as if anyone will see it as its downward firing.Unnecessary. EDIT: I can see that the painting is a sort of 'trade mark' of yours.To me its a waste of time/performance/paint.
ATTENSION (please don't color speaker cones it will add weight on the speaker and your speaker needs to work harder and it will not sound as good as before)
