[Box Design DD 2512]

Hello everyone. I'm new to the forum!! Here is my first forum post. I have 2 DD 2512s. I"m designing a box for them. Need help with designing. I have a slot port design already made up but I was more interested in doing a port down the middle. I'm not ready to do a 6 inch aero port yet. I'd like to stick with MDF all the way. Is .75 MDF thick enough for these subs? And when designing port down middle, is port same width once it branches to each side? and is length based on both sides cubic feet or just one side? is it treated as 2 single chambers or one single chamber when accounting for port length for tuning? Pretty much I need help with making a slot port down center. Pictures with descriptions and instructions would be great. If no pics detailed descriptions. Thanks! Box designs always welcome. max dimensions - 33.5 x 13.5 high x 23 deep.
