Need suggestion for center speaker with max 4" driver

[thewog]

I am doing my home theater for living room.
Unfortunately there not much space for center speaker max size available is (18 inch x 9 inch)

Also I am not very inclined to have separate subwoofer. Although i have selected some speakers but i am not sure.

I will buy parts from parts-express

With those drivers in mind I would use RS100-8 all round.

The rears in sealed 3L cabs and the fronts in ported 4.75L ones tuned to 63Hz.

This is going by a rough&ready ISDonline sim but I see no reason NOT to use the same driver everywhere.

I have 8" wide cabinets, and could fit in a 5 1/4" with no problem. Could have probably done six inchers too.
