Mike, my apology in advance for my reply here...nothing personal.
I completely disagree and I do based on personal experience.
I'm going on 2 years having my 21's built and I rotate my subs every 6 months (180 degrees) and have been using the same screws and same screw holes since.
My front cabs wall are double baffled and have 0 problems.
I blast the crap out of my subs EVERY day and I check the screws periodically to make sure they are tight!
Yes I'm anal about tightness
I have never had a screw loosen up or anything.
I screw using a very powerful drill until the bit skips. That's how tight it's in. I can't even overdrive the bit in !
Again this is my personal experience...big screws on MDF gives me no problems whatsoever.
