Well....

Here is the cloth side of the baffle. The cloth is on this side, the speaker on the opposite.

   

Now here is where the screws go that hold the speaker.

   

As you can see the screw head will be covered with the cloth. If the cloth is glued then the screw has to rip it to go in. 
If I want for this to not happen I need to first attach the speaker. But then gluing the cloth become cumbersome as the baffle no longer could be layed flat on the table because of the speaker.


It is possible the screws are hidden behing the cabinet opening and my worries are unfounded, but I have yet to look into this. Also unlike in many radios where screws merely puncture  small hole, these have to fully go under meaning that the hole is the size of the screw head which is large.
