Bung them down in stereo config near your mains , cross over at 80Hz and do a bit of math for the delay via the distance from MLP of speakers Vs subs .

But she sees cat walking videos on YouTube, and it gives her ideas:
And, you're right....I know I'm not going to get the sub dialed in optimally by ear.
But, for now, it's better than nothing. And, given my upcoming business travel and family vacation obligations, I probably won't have time to do it better until November when Thanksgiving rolls around.
Forget about it then till your sick of the sight of turkey and can't stand family a moment longer, Thanksgiving.
