I found one of these at my local music shop and saw this thing on the head. It appears that it opens, but the one I played through did not. My best guess is that it's some sort f vent, because it's permeable. Anyone know what this is?
Yup, it's a filter. Here's that the manual has to say about it:

Cleaning the Fan Filters
From time to time, it may become necessary to clean the fan filter. It’s a good idea to keep the fan filter clean to ensure maximum airflow, and cooling, through your LH Series amplifier.
To clean the fan filters, follow these simple steps:
1/ Remove the fan filter by placing your finger in the depressed area under the fan filter frame.
2/ Clean the filter with warm water and let the filter dry thoroughly before replacing.
3/ Replace the fan filter by aligning the frame to the top of the panel knock-out, and then, snap the frame back in place.
