Hey audioman58,
The very top two, wider then the bottom two pairs of speaker wire terminals, posts is were you can place different rated resisters to roll off the highest end frequencies to your personal taste. My pair were shipped with different valve ones. I have never had the desire/need to insert any at all because in my system the top-end is wonderful with no glare/sizzle at all.
