Yes, and it has the same depth, as well, which matters somewhat because it will be tilted.

You can angle it exactly the same as the 340SE, so use a Sierra-1 center.

How much is your CC-170 tilted upward? Tell me that (height in inches at the very front of the speaker), and I'll tell you how far forward you'd have to move the Sierra-1 in order to match it.
Running through some sample numbers ahead of time, the bad news is that you'd probably have to move the Sierra-1 so far forward that it would lose its balance. However, the good news is that the most your CC-170 can be tilted upward now is probably less than 10 degrees, which should be well within the Sierra-1 center's vertical listening window--in short, you don't even have to tilt it. By all means do so, as it helps avoid some floor-bounce in your case and it's better than nothing, but your new center should sound fine regardless.

It doesn't take much, and not so far that they'd be in front of the center speaker.
EDIT: I just noticed that the Sierra-1's measurements page is messed up, showing exactly the same graphs as the vertical bookshelf version's page.

What I said earlier should still apply, though.
