hmmmmmm
Yeah point on the metal plate and shorting the connection.
How about flush mount though on the high end line
Point taken on the sticking out also, it would make it 2"
However if they were counter sunk and straight, not on a angle
they would protrude a bit more that one can see peaking around and not moving the speakers.
I like the look of the clear ones however, maybe more depth of the red/black ends 1/8" thick on the end.
