If I add a 2nd sub, theoretically I will only have to use somewhere near about 1/2 the power on both than what I'm using for 1 now. IOW, I should be able to turn the level of 2 subs down to about 1/2 of where my 1 is operating at now. Yes? No? Kinda...?
I'm sure its a little more complicated than that but is that about the sum of it? or will I get into a whole lot more tuning issues by adding a 2nd...?
Thanks.

I used a single sub for years. Recently, based on positive comments posted by others, I tried stereo subs.
I would never, ever go back! Mind you, my room is on the small side and the mains are Lipinski 505's which roll off fairly high. So, because of that, my Velodyne DD-10 subs are calibrated higher than most set-ups. I was amazed at the amount of subtle stereo information comes from the upper range of the subs. They provide a perfect foundation for the Lipinski's, much better than a single sub did. With full range mastering towers, the stereo image would already be there right down to 20 or 30 Hz and in that case, using a single or stereo sub would make little to the the stereo field.
When our new room was tuned by the designer, we spent a lot of time trying the subs in different positions. The most useful ones were directly below the satellites, off the floor, and secondly, just to the outsides. Of course we tried the inside as well, just to be thorough. The clear winner and permanent position is now just outside and below the mains.
The other benefit is that there are very few "hot spots" as the stereo subs smoothed them out. I can't remember about the power difference but I'm pretty sure running two subs means that each one is working less than a single.
