where should i port my kick panels? they will sealed made with a combo of fleese and fiberglass.. the fleese is used to make the shape and the fiberglass is used for reinforcement. should i port the kick panels into the fender? (the little hole behind the trim peice where all the wires go into) or should i port it into the carpet? or should i port it into the car?? (which i think it would defeat the purpose of making a sealed baffle) this isn't a completely sealed baffle since i'm porting it.
the kicks are housing focal utopia mid-range and tweeters. the midbass will be mounted in the doors...

jonathan. aren't u proud of me?? i've finally started on my system.

 

why would you port your components?

 

ditto

 

because there's not enough airspace in the kick panels.

 

Hmmmmm. I'm not sure on this one, but there should be no need to port them, especially if you are using them for midrange only. Even for midwoofers, I wouldn't recommend porting them. And finally, porting is a process that, when done correctly, amplifies certain frequencies by using a properly tuned box and length-specific port. Don't do it!!

Because it makes sence.

It really depends on the shape and the space you have...But if you have room you can port it out the top to the underside of the dash, basically making a free air system which tends to work pretty good, when you have a semi enclosure back there, into the fender like ya said, the carpet, but really it comes down to the shape look space and such, but try like a 3" Hole saw in the back of teh glass into what ever you decide that should be good enough.

 

You can't just call a 3" hole a port. The port tuning is determined by the enclosure size, and port size. You will likely have some nasty port noise if you do this.

If you want to run it more free air you should vent it away from you, maybe into the fender. this way the back wave of the speaker will not interfere. Just make sure you dampen it as best you can.

 

so which one is better? carpet of fender??? i'm real greatfulfor the replies.. i gues maybe both methods are equally as effective.

 

Would someone please tell me what good (sonically) will porting a kick panel enclosure do, especially when housing a midrange and tweeter? I just don't get it!

Tony

 

True i should not have called it a "port" more of a vent.

One of the benifits to this, is similar to a sub, bigger lets it play lower...Most times...As for what is better, well like I said it depends on so much...basically try it and see how it goes. Also it depends on just how much tunabiltiy you have.

 

i'm thinking of building a "port" into the kick panels, it won't just be a vent. i plan to extend the port right behind where the tweeter will go. having a port will make the air flow a little more restictive so i woulnd't sacrifice too much tighter notes.
thanx for everyone's replies..

 

It's somewhat the typical Dynaudio aperiodic vent. Or scan-speak aero-port. A damped vent.

It is generally damped enough that the rear movement of the cone will not cancel out any of the front movement. A 3 inch port in an enclosure the size of a shoe box and houseing only a 5 1/4 mid would have a lot of trouble moving enough air to cause port noise.
