well, in newbie terms, you can call it "bass light" for them to understand easily rather than to give them complicated terms that will put a big question mark on their faces

IMO the ad700/900 won't really work out for movies unless you also have a subwoofer installed infront of you to "feel" the explosion and vibration effects on movies. You can pretty much imagine using an AD700 in an action movie and when explosions start popping out... youll just hear something like a spoon hitting a tincan very hard.
