830500 or 830844 for vented box?

[jpvt68]

Hi
I'm building a vented box for home theatre and music powered by a s400w 400 watt amplifier and can't decide on using the peerless 830844 or 830500, does anyone have any thoughts on which way I should go?

Why not post up the Thiele-Small paremeters of each or do some modelling of each?
