Here's some great speakers for the Tyros:

I used them with the Tyros 1 placing them on top of the keyboard. I guess they would fit on top of the Tyros2.
This is the original Chambridge MicroWorks model and it sounds superior to the MicroWorks 2 or 3.

I compared these with the Yamaha speakers and these were much, much better!

I've had a set connected to my computer for 5 years now. I've bought several "upgrade" speakers and returned them because the Microworks whooped them.

P.S. I am not the seller.
