Installed Weber 12F150 in DRRI...and a question

This is the speaker Ted recommended and the results are excellent - the bottom end is much more articulate and not boomy even with bass turned up. It also took some of the edge off of the Reverb channel. I was going to clip the volume cap but now don't feel I need to. Overall, the sound is very well balanced & rich. I did notice that I had to turn up the volume just a hair for some reason (maybe it's just that I'm old and the highs aren't as bright). My question - when I installed the Weber, it looks like there is a hole similar to 1/4 inch input jack on the underside of the amp unit - anyone know what it is?

That's your bias adjustment control.
