I just spent about 30 minutes searching through the forum for an answer to this question but couldn't find anything. Forgive me if it's been answered before.

I am considering upgrading my Sierra-1 LCR (+ D15SE) setup with the new Towers. Unbelievably, my wife prefers the looks of the towers to the bookshelf speakers.

The problem is, I have no space for the STC Center. What are your opinions on using the Towers w/ Ribbons with a Sierra-1 NrT center? For my surrounds, I have in-ceiling Sonance S623TR (which Dave recommended as a good choice of in-ceilings to match the Sierra-1s a while back.)

Thanks everyone!
