It has nothing to do with it saying Bose or Logitech.

I own the Z-5500, and I wouldn't think of taking it out on a gig unless my main speakers failed.

Look at the speakers. They're made of thin plastic. There are five of them. They got a lot of thin wires sticking out of them.

Whether it said Bose or Rolls Royce, the Z-5500 looks like a home audio system. It doesn't portray professionalism like a powered speakers do.

Also, from my experience, home audio systems do not produce the same volume per watts that a professional powered speaker delivers. My Eon10s were a lot louder than my Logitechs. I can turn up my Logitechs all the way in our small den, and it sounds loud, but not overpowering. If turned up two Eon10s all the way in my den, it would be uncomfortably loud.
