Re: Speaker fitment in Shoei X-11
I have successfully placed speakers in my X-11...I think much of the will work/won't work debate probably has much to do with differences in head shape, but I made it work for me.
In order to provide slightly more clearance, I placed the adhesive circles inside the helmet where I wanted the speakers to sit. Then, using the back side of a teaspoon, I pressed in a bit of the styrofoam, following the line of the circle. I ended up with circular indentations - probably not much deeper than 1/8" or so - which allows my ears to clear the speakers (barely). Less obtrusive than some of the methods I've seen so far, but it worked great (for me).
