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.

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.
I have a pair of Spica TC-50s I no longer use but recall having to snug every screw on them from time to time as the music would loosen them.
