Okay...rule <G30> a.

Mechanisms...so, if you had a whole kicker that was composed of lots of pieces that some of them were ABOVE the bumper zone...would it not be able to extend beyond the frame perimeter?

Or maybe it is trying to say that it can only extend beyond the frame perimeter UNDER the bumper zone...?

I am brainstorming, and I came upon this rule, and it started to worry me. I know there is probably no definitive answer to this, but hopefully there will be some clarity soon enough.
Your ideas are welcome... What do you think it means?
