OK, Look out Roger--- I may have to come to England to settle this. (Grin)

Logitech X23000 Made to be used with computers.
1-Two satellite speakers – small, about 5” tall.
2-One sub 8”
3-One control unit – Master volume and a bass volume (Sub)

Right and Left main outputs of the keyboard into a stereo 1/8” connection of the X2300.
I would guess you could cover a small room with 50 people without a problem – or you might just add a nice boost to your KN7000 at home.
I found that almost any amplifier I added to the KN7 seemed to change the quality of the keyboard. The amps seemed to have a sound quality of their own. The X2300 does an acceptable job.
