kam311 Posted March 7, 2017 Report Share Posted March 7, 2017 This is a theoretical question, as in the picture I am showing is not necessarily to scale. If it works out, I am going to use it in a design in a dodge single cab truck for my pops. My original intention was to keep the box a rectangle, but things started getting too complicated and this design could potentially solve all of my airspace issues. One side of the back of the cab has an extra two inches of space which would allow me to do a design as shown. Would the odd shape of this box and port cause me any problems? Or is this design something that would work and sound just fine? Thanks for the help guys so far...

neuspeedescort Posted March 7, 2017 Report Share Posted March 7, 2017 with the way it should load off the port wall and entry to the port has a nice angle to it and port end bracing you should be fine. you could always move the port to the left side and make it fold a couple times. as long as your port is large enough there shouldn't be any port noise.

kam311 Posted March 7, 2017 Author Report Share Posted March 7, 2017 Hell yeah, thanks man. This is the answer to all my issues I'm having with this box. I just couldn't get the tuning and port that I wanted with the perfect rectangle. The other side of this box actually has a bit of an indention as well, it's just a 1" instead of 2". I may actually run a folding port on that side. The extra space will allow me to do a bit wider of a port. I was scared to do the port on the opposite side thinking it might unload on me. But with some folds I am hoping I can prevent that. so far...

Lets see if this is more like it. I know the dimensions of the port might be difficult to read, but they come out to an even 36" like the plan calls for. If this checks out, it will be the one I use. It is my favorite so far. I tuned a tad lower so I could put in a 45 or two if I need it. Feedback is much appreciated. so far...

neuspeedescort Posted March 8, 2017 Report Share Posted March 8, 2017 make sure you 45 all the port corners. round over the port walls that make the fold. make it flow as seamlessly as possible. it will only help. i'd ditch that first little port leg on the right and just 45 that first corner. likely will not change your tune by but maybe a 1/2 an hz. and will be that much less port to cause any turbulence.

kam311 Posted March 8, 2017 Author Report Share Posted March 8, 2017 I can definitely do all that. I am actually tuned about 1/2 low anyways so hopefully the 45's and taking out those couple inches will bring me pretty close. I read that when the port shares a wall, it actually adds a little little length to the port by acting as a throat of sorts. I know I will definitely like the aesthetics more without that piece hanging off. so far...

Okay, now I think I have a pretty nice design here. I'm coming out .04ft^3 low on airspace, and maybe 1hz higher than I was hoping on tuning, but I hope those factors will be minimal. after all this set-up is just for music and will never compete. I am also hoping that the 45's in the port will lower the tuning a little bit by creating a bit less port area. Are the 45's I have mocked up sufficient or do I need to make them a little larger? These are basically just 45 degree corner cuts. I can make them bigger if I need, and it might even help gain a bit lower tuning, I just don't want to cause a problem if the turns of my port are going to restrict the airflow. I guess if it really comes down to it I could do a 2 3/4" port instead of 3", but i liked the sexiness of the 3" port. so far...

kam311 Posted March 10, 2017 Author Report Share Posted March 10, 2017 Would creating a throat be better for the flow of the port? Would it ruin my tuning too much? if so, Ill leave it how it was. so far...

ShadeTreeMechanic Posted March 11, 2017 Report Share Posted March 11, 2017 I would do a straight port or an "L" port. I wouldn't want a port with a bunch of 180s in it. Your first design looks ideal. Ports that have 3 walls in common with the box are the most efficient use of space also. 91 C350 Centurion conversion ( Four Door One Ton Bronco) 250A Alternator (Second Alternator Coming Soon) G65 AGM Up Front / Two G31 AGM in Back Pioneer 80PRS CT Sounds AT125.2 / CT Sounds 6.5 Strato Pro component Front Stage CT Sounds AT125.2 / Lanzar Pro 8" coax w/compression horn tweeter Rear Fill FSD 5000D 1/2 ohm (SoundQubed 7k Coming Soon) Two HDS315 Four Qubes Each 34hz (Two HDC3.118 and New Box Coming Soon) Link to comment Share on other sites More sharing options...

The best I could do would be something like this I think. I don't mind it, I was just worried about the indention on the back of the box interfering. That why I came to ask from the more experienced ones. I felt the other one guides the air a little better, but really... what do I know lol so far...
