RCA connectors-how to tighten them up.

You're right. I give that advice to others. I should have taken it myself.

On the AQ Sky, one can unscrew the silver end cap over the RCA barrel and there you will find a very small screw that can be tightened to increase pressure on the outer RCA connectors(flaps). Or, one can take a small jewelers flat blade screw driver and push it in between the outer connector contacts(flaps)and the barrel. 

Either way has worked for me with no issues. Also, if you have good soldering skills, you can change the batteries in the Vandersteen crossovers but only if they're out of warranty. If under warranty, send them to Vandersteen.

PM me for the procedures to change the batteries if you decide to go that route as there are some specific items/procedures that need to be followed closely.

Back in the day you just bent the center pin ever so lightly to one side.

Thanks Ken, I never would have found that.

You are really at the mercy of your components, and most of them use female RCA's from Taiwan.  Some companies offer locking RCA plugs. You may want to have your cables re-terminated with those if your connection is poor.  The system is only as good as it's weakest link, so don't let that be a connection point.
