Poor match

June 15, 2016

Both of these items are good product. However they do not match. The Polk db651are just slightly bigger then the adapter ring. You cannot match the screw holes together, if you match one the others hang off of the ring. Also the adapter ring sits right on top of the ring at the edge of the speaker and it should not even touch the speaker itself, only the mounting steel. Again, great items but the match is incorrect. I think the Metra adapter ring 82-9601 will be a better fit.
