I have a mirage system M3 si and mirage center etc. I would like to set up a wide channel and having trouble deciding on a the wide speaker. The room is huge 19 x 32. It is a dedicated audio visual room and the use is mostly HT. The amp is the onkyo nr 5008 I am thinking of using one of the om satellite for the wides

Since it's pretty much a part of the front soundstage, rather than the sides or rears --based primarily on location, not the signal itself -- I'd try to match it to your other fronts if you can.

The problem is the Mirage M3si are long out of production and they are huge tower speakers at that.
