go!

They act like a controlled leak in your sealed box, making it act like a larger sealed box. Useful if you need for saving space. By varying the amount of stuffing in the vent, you can change the apparent volume of the enclosure.

Forget about whatever other magical sq properties of aperiodic enclosures you may have heard. That's pretty much all it is.

Do certian speakers fair better in an AP enclosure?

 

[Derek]

audionutz did a good writeup on ECA somewhere about AP installs.....very good read...

 

[muppetwagon]

yeah...i should read that one again....

If I remember right...there is a T/S spec that has something to do with it. I'll give it another read.

 

[npdang]

I think audionutz did a good writeup, but IIRC there were some technical things that weren't correct.

There is no speaker that fares better in an AP enclosure per se, although speakers that need a LOT of space for a given alignment will of course benefit more than speakers that require smaller box sizes.

It's basically a controlled leak in a sealed box, that makes the box act like a larger sealed box.

Now would this be useful for a cone midrange, fiberglassed into an A pillar? Or not at all?

Thats what I was thinking of. If I can find somewhere to put it, I was thinking of using the dayton RS 5" mid with an aperiodic vent because I dont have anywhere near the required airspace for the driver. It wouldnt be perfect but every little bit helps.

I am certainly no expert but it seems that the sealed box returns the energy of the speaker back to the speaker while a aperiodic vent absorbs the energy of the speaker. If we use a car anology the cars spring is the sealed box and the shock is the aperiodic vent.

I don't know which is better but I would suspect that they would sound different.

before i installed my focal 6w2,s in my xterra 8 mo ago , i built a small sealed test box and installed a 4 in scan-speak vero vent at the rear of the box just to see if there would be any improvements in overall mid clarity and low end resp. but it didnt take long to realize after listening it wasnt what i was looking for ,midbass was tubby-midrange distorted at med output levels,it could be due to the focals very high qts around .74 ,it sounds much better in the door,midbass still a bit tubby though

So any other ideas on using an Aperiodic Chamber for an A Pillar Mid install. Anyone experienced with this?

NewTitan, wanna try this in your A Pillars?

 

[npdang]

I'd just leave it IB. The only purpose to an AP vent is to give the enclosure more space, and you can't get more space than IB.

 

[JohnSmallberries]

What about using aperodic vents for midbass speakers in doors you can't properly seal up? Would it be feasible to do? Or would it be better to make a sealed enclosure out of fibreglass?

 

[npdang]

It's always easier to just use an eq to boost lower frequencies, especially for a mid/bass than create a sealed fiberglass enclosure.
