I got torque settings from speaker manufacture and use blue loctite on the threads to prevent back-out. You will need a micro torque wrench.
Anyone tighten up drivers occasionally
Out of curiosity I checked the tightness of the mounting bolts on my Revel speakers today. Probably the 2nd time I have done that in a decade. I could turn each bolt maybe 1/16 of a turn (curiously, one woofer bolt took a 1/4 turn). Anyone check their drivers on occasion? systems been off since, and wonder if I will hear anything different-
