just a quick heads up.
One thing I found with applying micro or transpore tape over the top of the edges there is that if you are doing it to hold down the felt for example, it gradually peeled off over the course of time off the edges of the raised driver housing. Directly on the damping fabric may be ok though..
Now what i do is fully apply thin strips of doublesided tape ( stuff where the adhesive won't bleed into the stock damping paper. ) over the crossmember frames of the "driver squares", and then press whatever cut to size felt dampers on top like that, so there is no arc below against the driver, everything is held tight to the driver surface so as little bleedout into your other zones occurs.
You'll want to make sure it is decent double sided tape though.
In a Realistic Pro30 mod I used some that gradually wept/melted out into the stock white damping and sealed it off "all goofy like" so i had to take that off. Art supply stores might have what you need if you try this way, and apologies this has been dealt with before but like everything it is buried in the thread, which is why for ideas the BMF pictorial thread is good.
phew. there done.
