Tony. Sorry, no. The Tyros TRS-MS01 Speaker System (2 satellites + sub) won't work on the PSR3000. They were specifically designed to work with the Tyros only. The TRS-MS01's satellites & sub don't utilize the standard 1/4" L/R audio outs of the keyboard, but special Tyros specific audio outputs instead. In addition the TRS-MS01's include specially designed mounting brackets designed to mount the speakers onto the Tyros only.
