What would be the best way to go about angling the speakers in a door-mount application? I ask this because my speakers by stock configurations fire away from the passengers and they need to be angled to fire towards me. Would two smaller MDF spacer rings work? Or better yet, has anyone found already-angled spacer rings? I can't find any.
I was thinking of possibly using two rings, and putting something between one end of the rings to create an angle. They would then need to be sealed off as well. What is the best option here?
