I just got through installing an Infinity Kappa 32.7cf into my front center channel and thought I would post up a few pics showing the install. The other speaker is available for sale on the black market forum.

Here's the whole speaker attached to the backside of the speaker grill.



In order to get the speaker to sit flush, I had to trim two of the ribs on the backside of the speaker grill. This picture below shows how I had to trim those ribs just slightly enough to let the speaker sit down on the other uncut ribs.
