Nope. That brass weight ("tone extender") is on the end of the low tenor, to
help smooth the transition to the bass. The unusual bass sound is largely
due to the strike point. Most pianos maintain a 8:1+- strike ratio through
the bottom third (or so) of the scale. The strike ratio of the 6000
continues to change through the low tenor and bass, ending at something like
6:1.
