[QUOTE="Buck, post: 8812957, member: 591582"] Yeah I wish I could design it for you. My health is just garbage, and I’m in constant pain 🥲 If you’re going to do 32 hz, which tends to be a great daily tuning for most, then I’d just make sure you wind up at 3.5 cubes net. One option you may have is to side fire a 6” flared aero to keep the port situation easy, keeps the box smaller, if you think a side firing port could have enough clearance from a side wall. Sundown’s recommended port area per cube is about 14.9, and I’ve done anywhere from 12-16 per cube with those with square/slot ports for ported. If you truly have 2000w+ for amp power, you may wanna stick towards the 14-16 port area per cube. One thing is your box will be a little smaller than 3.5 cubes net, if that program doesn’t take into account the sub displacement. If not, then you need to keep the port the same and just add some more chamber space; iirc it’s about .1 disp for each sub, so you’d want 3.7 in the chamber to wind up at 3.5 net, but keep the port the same as the box you have now. The box looks proper, otherwise, based on the numbers I’m seeing from it. I would recommend adding something like a 1.5-2” x 15.5” brace in between the subs, if it’s a single baffle, because that’ll keep the baffle from flexing and degrading over time. The sub box you have designed, is it going to fire all to the rear? [/QUOTE]
