Welcome man!
Don't worry there are other college kids that hang here also, man I miss those days.
I've not owned the m3's or m22's but they both have a great reputation. Maybe some others will chime in soon.
Consider ordering from the Factory Outlet, it will save you 10%. Also, if you buy 5 or more items, including any accessories, you get another 5%, this may help in your purchase decisions.
Factory OutletThe m3's and m22's have very similar specs. The m3's have one 6.5" driver versus the m22's dual 5.25" drivers, but I think they both have great bass when combined with a sub for the freq's below your crossover setting of 80hz. The m22's are 1dB more efficient and handle 25more watts each, but those figures aren't a huge difference.
For that size room I would think the EP175 would work fine. The 10" driver won't move as much air as a 12" driver, but it should work out fine. I've owned an EP350 prior to my current EP500 and was very happy with its performance, now I have an EP600 on the way.
good luck...
