Doc-z,

There has been much discussion about using the Logictech speakers. I use them at home for practice and out for small jobs such as nursing homes and small private parties at country clubs and restuarants. I use the Z2200s and they are perfect (IMHO) for groups of 0 to 60. There have been a couple of disenters to this opinion but I would say there are 10 satisfied users for every one dissatisfied. You can check prior posts for opinions. I believe this system is 270 watts RMS.

Gary Diamond and a few others use the Z5500s which are 5.1. I haven't heard of any dissatisfied users of the Z5500. I've heard of professionals using them for crowds of up to 150 with excellent results. I believe this setup is 550 watts RMS.

I never would have believed it either but I heard them being used first hand with my own ears at the San Jose Synthjam in May of 2004. We were in an activities building at a mobile home park. They easily filled the whole room.

My Tyros does not have speakers. These two systems (the 2200s and 5500s) seem to be much better than the Yamaha Tyros speakers. These systems have more than enough bass and the drums and vocals really are clear and crisp. A couple of people on the forum felt that these systems lack mid range. Check out prior posts.

Setup is a breeze and with the the 2200s I can carry the whole system in a large gym bag.

I hope this helps.

Tom
