i am not done with the stacked ports yet.  They are made of 1.25" MDF and there will be 12 or more total on each side.  The box is supposed to be tuned to about 32hz.  I could easily tune it way lower but i don't want this box to miss out on some of the upper bass frequencies.  

 

Also, i am NOT DONE bracing this thing yet.  I wanted to build the bulk of it and then decide from there what i was going to do to make it sturdy.  It is already sturdy the way it sits but i will do more for sure.  Stay tuned! :D

the box is: 18.xx ft3 (ID) before displacement.  The ports are 75" Each and iirc i think i they will be at least 15" long.  The stacks are made of 1.25" MDF each so i am starting with 12 of them.  Again, i am doing more bracing and NONE of what you see is glued, screwed or tattoo'd yet.  It's all a house of cards about to fall over any second now.  I will start gluing and shit as soon as i decide the direction i am going to go from here.  I don't think i am doing an acrylic window this time.  I just want it to be a really nice box that bangs.  Perhaps i will sell it someday when i am through with it. Stay tuned!

the ports are a MONUMENTAL waste of material.  BUT...the 1.25" piece of MDF i have is already ruined from water damage on one end of it. If you look you can see what i am talking about.  So i decided to chew it up with this stacked port.  It looks like 2 rectangle ports, and they mostly are, but being stacked allowed me to also give them a different shape. They have little 45's in the inside corners built in.  They look kinda cool in person.

This box used up SOOOO MUCH wood it is ridiculous.  Here is what it looks like from one day of cutting.  That 3/8" upcut router bit ain't no joke, it is HUNGRY! lol

I decided to do a skeleton type stiffening system (bracing) and then attach those to each other via another brace.  The entire box except the top and bottom will have it.  I STILL am not done yet but this is the direction i am going.
