Does anybody have these?

The review in Sound and Vision sounded pretty good. But they are all ported enclosures except the center - does this cause any problems?

What about the sub? At Circuit City when I went to look at these the "salesman" did everything he could not to play the Infinity and when he did I could barely notice it.

Any information will be helpful.

I am sure it was a problem with the setup. You were at CC! When you listen you have to make sure and check everthing. The sub is easy to set up bad and difficult to get right. Then add the room and you can bet that it is not at its best.
