I have read many times to set your speakers to small and x over to 80 if you have a sub. Unfortunatly i dont have a sub yet. I have my Studio 20V4's set to small and x over at 80 with the bass set to front is this the correct setup. I didnt know what to set the bass for it said sub yes or no so i put no and put bass out front. I assumed that meant the bass is supposed to come from the Front Mains or am i incorrect. Please advise
