Maybe at some point the Monoprice THX-365C will take the place of the (currently non-existent) Infinity RC263 center. It is the same price, but is lacking a full spinorama.
Nonetheless, audioholics rated it very highly:
The Monolith THX-365T and 365C are some of the most inexpensive THX-Ultra certified home audio speakers to ever have been produced. How do they perform? Read on to find out.

Could it have an honorable mention in the mean time? (being vetted by THX and audioholics)
I do not know whether it goes on sale or not during the holidays, but I would expect that would be the case.
