I have actually built quite a few boxes, and they have all sounded great, and never really had any probs. BUT, i dont usually do slot ports, never quite clicked with me, I've preferred aeroports. So, i dont mean to come off as rude, but Instead of criticizing, why dont u help me learn how to do slot ports so I can get better? I would love too, but my pickup is a daily driver, still gets used heavily as a truck, and I regularly pull a trailer. i kinda need my back window LOL

I have been considering going back to aeroports also. Slots are best for when U actually have room. I just dont want the expense of them. I literally just built ym last box, and it broke along one of the seams. I underestimated the level 4 m2's, and didnt add enough bracing. I was running a box that was 46W x 21H x 16D, 1/2" indents, dual chamber, and 2- 3" aeroports per chamber. tuned to around 30 hertz. It sounded awesome, even got me my first noise ticket lol, but then I played rack city, and the box broke on the driver's side seam. I dont wana fix it, cuz I wana make it a bit bigger, tune a little lower, and im afraid its prolly just gna break again. Or leak.

I dont have much of a choice on box size. I have a very limited amount of room, and I need to just make the best of what i got. What about the slot port displacement and volume thing? How do i figure up the tuning if it changes the volume, and the volume changes the tuning? Its like a catch 22.

sorry yall lol. I am running an audiopipe ap30001d. Ive got big 3 upgrade and then some, 250 amp alt, and yellowtop under hood, shuriken bt120 in back. My old box broke, and I had 2 3" aeroports per sub on it, dual chamber. redesigning to a slot port and subs up. Old box was ports and sub facing seats. Ive modeled it nuumerous times in autocad, but everytime I think i got it right, every port calc on the web gives me a different number lol.

m2 And if I change the port width to 5", I can get the tuning freq where I want it. BUT, im still not getting port pieces from the calc

I am trying to build my box for 2 15" DC level 4 m2's. They will be in a 96 ranger extended cab. i am looking to do port up subs up, port on driver side, subs on passenger side. I have 48"w x 22" H x 16" D to work with. The sides of the box will be indented 1/2" for capeting. I have a couple problems im running into. I've posted a pic of the torre's calc, and it wont give me port pieces. Also, the12volt.com is giving me the 32.5" port length at 28 hz, and torre's is giving me 33 hz at same length. Whats the deal? second, when figuring port displacement, I have never quite understood it. When u subtract your port from the box volume, u have to recalculate your port again, which changes the displacement, right? I feel like im running round in circles with it lol I know the volume is a little on the small side for the level 4's, but its all the room i got without getting into a wall or covering my back window. Truck is a daily driver. If u need more info, ask and ill be happy to answer Thanks in advance for the help!!
