UD,

That KB is not going to sound the same in Mono, when you play a hammond sound hows it going to spin left to right.

That setup is OK for domestic home use but is it any good in a big room with sound absorbing sufaces.

I don't think that you can play a KB in mono it will sound dead.

Why did Yamaha put two speakers inside the KB , why not one right in the middle.
