Subwoofer wall; port placement.

[kdeezy]

I've seen pic's of walls built In various vehicles and the question I have is, how critical is port placement when you wall your vehicle? Are there advantages to having the port In the center VS left or right side of the wall VS top or bottom of the wall?

Go to the search option and search " wall help" and click the one that says wall help and every thing you asked is in there. Good luck with the build!

Port ondriver side meters better because it builds pressure on passenger side.

Port in middle is good for an "equal" pressure on each side of the cabin.

Top or bottom ImO is when you can't fit the proper port on the side lol.

Thanks for clearing that up for me

For my wall I was able to gain a couple cuft extra just posititioning the port along the drivers side.

The walls I've seen built with the port on the driverside were competing in a format that is sealed and puts the meter on the glass, the ports along the top were competing in USACi where the meter is on the floor and the door open, and port in the middle I've seen more with demo systems and groundpounder systems. If you're building for fun and just demo's I'm sure you can do it whatever way you want.

Depends on your goal and space available, for me, it´s impossible to wall with 4 18´s my explorer and get a good amount of port area, so i´m building a 6th order, on my friend´s almera we did port on the middle because he competes at bass race (over here we do it with driver´s door open) and that´s why he didn´t built port on driver´s side, and lastly, i built a few days ago a wall on a suzuki vitara, the guy wanted that thing for demos all day long, he wanted to get as loud as he could to passenger side, so we built port on driver´s side and man, with his door closed the passenger´s side is nasty!!!

Tons of people built port on top because it´s the best sounding according to them , i haven´t test any port on top of a wall yet since i´m still a noob about walls, you should get a better input from someonelse

fecupe your driver side is on the other side of the car from ours isnt it?

Port area/placement is irrelevant unless you know the thiele small parameters of the woofers, how much power is available, the airspace inside of the enclosure, and the desired tuning frequency.

edit: port area/placement IS important, but without those other factors being known, figuring out the correct port area or location for the application is impossible. You cant make sure the panel resonance isnt in the lower frequency range without that data.

One SMD in a trunk of a Grand Prix, I'm going to re-do the whole box, put the driver in the middle, and put a port on both sides, if I'm reading this right, and block off one port, I will go from 35htz for daily to about 45htz for comps...
