Should be fine, but make sure of 2 things.
Def. Techs come in a #1 and #2 so that you can either have the subs pointing out or in. When I originally ordered my 70001 SCs from Magnolia, they sent me 2 #2s. I called them out on it. After some inquiry, they realized that multiple customers were out there with either 2 #2s or 2 #1s. It isn't a big deal, but not something that should be overlooked.
Turn the bass knob on the back. One of my original Def. Techs. had a problem so that either the bass was on at full volume or completely off. volume should be able to be controlled gradually.
Other than that, I'm glad to see you chose the 70001 SCs over the 7000s and the CLR 3000. Excellent HT speakers.
