I have not encountered that Madison speaker, however it doesn't look very exciting. According to the specs the crossover point between the 15" drivers and the horn is 3500Hz. There is absolutely no way that the 15" will perform well to that high of a frequency. It will be beaming like crazy. Yuck.
I have dealt with most of the EV eliminator series and while it might appear to be a step above Madison, I find that entire series very mediocre.
Honestly I would look elsewhere, do some reading here on these forums for a while to get a feel for what will work best for you. Post in the lounge with what you are trying to do, what your budget is, the types of rooms you do, etc. As much detail as possible.
Cheers
