using 2 centers as mains


I have a combined 2 channel/ht system and my mains are Heron i's driven by Rogue M-180's.I thought I would try saving some juice and tube life so I am waiting for the receipt of another matching center(Meadowlark Pestral).I figure I will set these up as my mains and go with the phantom center setting.
Make sense or am I doing something stupid?

Thanks

I will be hooking the Petral's up as the mains, horizontal not vertical, and the reason I save on tube life is the tube amps/tube pre will only be used for 2 channel now. I have a Rotel that will be driving the Petral's and the rear's.I should have explained this before.(and I'm probably still not painting a clear picture)

Using them horizontally is decidedly sub-optimal. Your phantom center imaging will suffer.

I could try them Verical but this will depend on the WAF. I better start priming now, before the new one show's up.
