Disklavier

I have had the Mark IV for just over a year.  We find it is too loud at its 
lowest settings to allow conversation, even some distance away in the 
kitchen.  We enjoy listening to it, but it isn't going to work for a party. 
We have it in very large space, so the room may be too hard, but?  I am most 
interested to learn if the baffles sold will work in this unit, given the 
electronic array.  We would use it much much more if we could find a 30% 
reduction in the lowest volume.
