Thanks for the link Steve. I have the MSP5's already and I have been thinking about maybe getting the SW-305 Subwoofer. It would also require some type of stand for the MSP5's (for Gigging). Plus there is no carrying case for the package like I mentioned in my previous post. Plus I wanted to be able to use my MSP5's in 'conjunction' with the "supercharged" speakers - that would be hooked up to the proprietary inputs and outputs on the back of the Tyros. That would give me more bang for the buck I think because I would be implementing '4' speakers plus a Sub instead of the MSP5 YST bundle (2 speakers + Sub). The supercharged speakers + Sub "AND" my MSP5's. As we all know the Tyros does NOT have standard Aux Outputs so the only way to fulfill my 4 speaker needs (supercharged + MSP5's) would be for Yamaha to make a 'supercharged' speaker system and I could use the Main Outs for my MSP5's. Voila!! 4 speakers all running at once in Harmony.
The MSP5's and YST bundle would be a solution but not the solution I was hoping for and wanting. And of course from my previous post you know that I think about the current Tyros speaker set: it's not up to snuff IMO. But since Yamaha used proprietary inputs/outputs, ie., "hookups" - (from what I understand anyway) a 'supercharged' speaker system would be the ultimate expression of a fantastic sounding Keyboard and the only way I could obtain my goal, ie., playing the Tyros on a fantastic 3 piece speaker system plus using my MSP5's, etc., together!

Best regards,
Mike

PS: I guess from your post Steve that the MSP5's & YST Subwoofer is the only option Yamaha intends to offer. That and the current 3 piece speaker system offered for the Tyros. SAY IT ISN'T SO STEVE!!!! I know you have an 'in' with Yamaha Steve. Any chance???

Best regards,
Mike
