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.
