as the title says this enclosure is for 2 12" mach 5 audio spl subs.
dappa5 helped with doing a couple dimensions and the port lengths
dimensions were 38w x 15h x 20d but forgot to tell dappa i wanted
a double baffle i just added it on and cut the interior depth to 17.75 instead of 18.5 comes out to 5.06 cubes before woofer disp. port disp and bracing will be done with threaded rod.
tuning points i have are 36hz,38hz and 45hz
i want it at 38 for daily but wanted to try 36 to see if there was much difference so i have that aswell and now onto the pics
