How to set up REL T-9 with Magneplanar 3.5s?

Hello. I recently purchased an REL-T9 here on Audiogon to use with my Maggie 3.5 speakers, replacing an older REL Storm. And, I was asking if anyone has set up one of these with Maggie speakers who might be willing to give me a few tips on set-up and adjustment. Thanks!
I have just ordered a pair of Gallo Acoustics 10 inch subs to use with my 3.7s. I'd be grateful to hear of anything you learned in trying to integrate the REL with your Maggies.
