REMINDER: tighten up your loose screws

REMINDER, tighten up all loose screws around the drivers. Just Do It. All of them.
Sit back and enjoy your “new system”.

85% of screws on my speakers needed 1/8 to pass 1/4 turn to snug firmly and guess this… all screws on my woofers needed 1 full turn. Some was actually needed 2 turns. Anyways, improvement was a jaw dropping.

Sadly, it appears to be impractical to to tighten my screws any further - at least the spousal unit claims:

 "The tighter he gets, the looser he becomes..."

Long time ago when i used to have speakers with back panel attached with the screws I didn’t go crazy screw them extra tight, I just used nail polish to put them on. Nail polish is easy to unscrew if you need it and at the same time it holds screws on the place tightly.. don’t use glue as it will be permanent. 
Nice trick surfmuz. I had thought of using the blue thread lock before but that sounds like a good idea. I’ll use the thread lock for my fingernails instead.
Yah, the blue thread lock is good too but it’s an extra non necessary move like buying, spending and nail polish is always there in your wife’s medicine cabinet waiting for some real purpose  :)
Good info here about tightening speaker screws. Many speaker manufacturers would use only wood screws into MDF, so gentle tightening 
is critical. Years ago it was recommended to take large woofers out and rotate them half a turn because of sag from the weight of the driver on the surround. This would help prevent damage to the voicecoil and gap.
