does it matter what size box a 6' duct empties into

andrelaplume2July 16, 2012

I tried to post this question earlier but I think I confused people. I have a 6" duct that ran into a fully open 10 X 10 box in my rafters in my unfinished basement.

The basement is now almost finished. The 10 x 10 box does not fit with my ceiling grid system.

I can run the 6" duct directly thru the ceiling tile with a 6 " round grill.

Alternatively, I can run the 6" duct to a 10 X 6 boot and have a 10 x 6 grill. Is there any benfit to one or the other in so far as air movement or is all asthetics?
