Guys - You just need to experiment with it and find what works for you. Depending on the system and your preferences, you may want to tweak it differently. I believe this is why it really hasn't been spelled out in terms of what you "
need to do". Based on what's been said by quite a few members, I think the majority of us are currently running the trapezoid piece and the rug liner, but are not using the ring around the driver. Here's a bad phone pic of what I've been using for the past few months (I may try retweaking it soon, in order to cover a bit more of the metal ring around the driver):
Can someone supply a better template for the rug liner? It looks like the pdf is from a picture of it inside the cup, not taken out and laid flat. When I try to use it to cut the liner, it doesn't really fit right.
The template's a starting point; work the shape in to something that you can fit. I cut mine around the trapezoid so that it fits the curvature of the cup better. I use 5 small pieces of removable 3M double sided Scotch tape to hold it in place. Stays in place and can be easily taken out for cleaning, etc.
So theres two layers? The rug liner on top of the (adhesive) foam?
Correct. Adhesive foam down first (whatever you choose to do there) and Rug liner second.
