6 of these and a half dozen of another. 1.5 inch front baffle just like the plan Danny sends out. Four ribs in the middle, baltic stains well and is easy to match to speakers you may or may not have. I like baltic because of the staining and painting ease, limited dust-MDF is terrible, I can get it easy, like the density, enjoy some grain look, but I can not speak to Brian's cabinets since I do not have one. Others? Differences, maybe none, I don't know.
