How do you guys clean dust/grit inside the longer horns?
My L300's LE85/2312 horns have spidey webs and what looks like grit inside them, primarily in the silver-colored couple inches at the extreme rear in front of what appears to be a screen. A vacuum pulled out the webs but not the grit, just swirls it around. I do not want to damage the driver diaphragms with a pointy tool or push the vacuum too far in in case it hurts the driver. I don't really want to pull them apart.
