Here are instructions
for mounting your speaker

How to install your speakers for maximum tonal enjoyment.

When mounting your speakers, use caution. Vintage style frames (thinner) require that you mount the speakers using an X pattern method.

A) Tighten all bolts/screws finger tight till the bolt meets back of the speaker frame.

B) Hand tighten in a cross frame or X pattern like a head gasket on a car engine. DO NOT TIGHTEN in a clock-wise circular fashion as you can warp the frame.

C) Tighten 1/4 turn on each bolt in an X pattern in one pass, then the other 1/4 to 1/2 successive turns in successive passes. This will compress the gasket enough to ensure a proper seal, and without warping the frame. I recommend no more than 1 full turn after the bolt meets the back of the frame, usually 2/3 to 3/4 is good.

Failure to do this could result in a damaged cone, bent frame, or unusually high shrill, or muddy bass noises from over-tightening.

DO NOT USE AN ELECTRIC DRILL SET TO A TORQUE SETTING!
