Looking for some advice on subwoofer placement for a 7.2 setup. My subs are currently set in the SW2 and SW4 locations (see picture). Problem with SW4 is that it's in a closet and the majority of the subwoofer sound stays there rendering it worthless. Not to mention the SW2 location, due to the L-shape of the room, does not quite fill the room. I want to try some alternate setups but before buying/running the cables I thought I would get your input - I realize sub placement requires some tweaking as every room is different but what do you think is the best starting point? Note the subs are not matched - the larger is an Onkyo SKW-940 (12"), the other a Polk RM 6750 (8"). Suggestions on which sub I should use at which location are also appreciated. Thanks for your help!
