Box size with high pass?

I am designing myself a center channel and had a question on box volume. This will be used with the high pass from my reciever set at 80htz. Does it matter what size I choose if all the F3's for the recommend box sizes are below 80htz anyway? Any negatives of building it to the biggest size/ lowest F3? I do prefer the larger size visually. The woofers will be 2 Silver Flutes 8" 4 ohm crossed over at about 250htz or so.
