Hey Terry ... wow!! Sounds like you found a really nice setup there. Glad you like the AL's!
And to tonkan: seems I misinformed you. The Tyros has speaker outs and line outs. According to Yamaha you can only hook their speakers into the speaker outputs. But you can plug any powered speaker system or amp or home stereo into the line outs.

Have fun with your Tyri y'all! I just got me a used 9000 Pro and man that puppy rocks!

Blessings,
