Eminence PX-LPAD Problem

[Myth_103]

Hey guys.. Strange and I'm sure ridiculous question. I'm helping a friend assemble some home stereo speakers and he's using the PX-LPAD for the tweeter. But the problem is, I can't assemble the thing to where it fits together tightly. I just assumed you pushed the knob on the front and it was together. However, it's loose in there.

So what am I doing wrong? Surely I'm missing something simple with these 3 pieces!

Have you got the nuts tight ? You should have a nut on either side of that plastic cup and The L-pad should be tight before you push the knob onto it .
