I think as long as you have baltic birch, your speakers will sound fine. They'll be lighter and more durable than MDF cabinets too.
I like to put four π speakers on 14" stands with 7° tilt back (pointed slightly upward 7°). The three π stand is a little shorter and tilted back a little less: 12" and 5°. Stands made this way will put the forward lobe right where you want it to be.
Don't put the speakers on stands unless you're running flanking subs. If you don't plan to use subs, put the speakers on angled risers, on the ground with the front about 3" and the back about 1". This will tilt them back and will avoid boundary self-interference. Push the speakers all the wall back to the wall behind them too.
