Cheap tweak from Virtual Dynamics:

Hope I ordered the right one!

I think you'll be fine. I just did a torque test on one of the original screws on one of the midwoofers and it was about 10 lbs. Actually, I pre-tested all four screws on a mid-woofer driver and all four were slightly different. Hmmmm... interesting. Also, a correction: it is inch-lbs. not ft.-lbs. Even if you don't hear a dramatic difference, you can always use the Fat Wrench for your hunting and target rifles. Or if you don't hunt or shoot, it would make a great gift for a relative who does. (O: Let's have some fun.

Perfect stocking stuffer for Uncle Jed Clampett.

Might as well make sure the screws stay torqued too.

I torque screws on my spring guns (pellet guns), and use vibratite to ensure they stay put. One of the nice features of Vibratite as a thread locker is that the screw can be removed and inserted several times before it needs retreated.

The Vibratite is the missing link, I think. I have always wanted to tighten my drivers' screws, but I always thought I would just keep having to do it, and that they would eventually strip. Great solution!
