First of all you should never indicate speakers as Large unless they can produce below 20Hz (which is very low), otherwise always set your speakers to Small.

Second, did you also indicate in teh setupmenu that you have a subwoofer? Because if all speakers are set to Large some receivers will omit a subwoofer because Large indicates the speakers can reproduce all sounds even below 20Hz.

So walk through your setup menu, say YES when the sub (SFW) is asked for and that should do the trick.
