Placement of Dual Powered Subs with Tower Speakers


Just purchased a second REL S/5 Sho. Main speakers rated down to low 30's...I know exact placement was crucial with single sub, wondering if just as crucial with 2...

I have nothing against measurements and modelling and use both extensively myself. But not everyone has access to such, so I have suggestions which do not require them.

Thanks to both...the only placement obstacle that comes to mind is there is a single available electric outlet though I think it’s in a good place. Thoughts on long power cords? Thanks again 
The comments thus far seem to presume forward facing woofers. Currently, I have SVS subs that fire down
