Polk db690 : midrange/tweeter question

[bluzrip]

I just received a new pair of db690's. One of them has a loose midrange/tweeter module on the post. Rotating it slightly (about 30 degrees) snugged it up. But now it is out of line with the bass cone which may contact it in large excursions. Is there any way to adjust this?

Peel off the sticker half-way on the back, or poke a hole through the middle. Turn the bolt clockwise to tighten the post. These are usually bolted in, and will usually be epoxied where they cannot come loose. You say 'new' maybe a return would be in order? No sense in screwing up the warranty if you've got one.
