Egg Carton Foam Question

[Decado 10+ year member]

Ok, so soon I will have a ologyaudio component set and I will be putting the midwoofer in the door. I know I should be using some egg carton foad or a deflex pad behind the driver, except this proves to be a problem because the speaker location is near the top of the door so i can't just have the foam sitting in there because it would interfere with my window. Now, would it work if i had the foam egg carton attached (glued or something) to the back of the panel the speaker screws into with enough slack on it so that I can put the speaker in with the magnet just touching the foam?

Ahh, ok, sounds good thanks.

Edit: Is that going to work the same as egg carton foam or a deflex pad?

Deflex pads are very thin. I can't see how those would interfer with your window operation at all //content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif

Do i glue the edges of the deflex pad on the backside of the panel the speaker screws into and when i put the speaker in just push it back?

No man.

A deflex pad is installed on the wall opposite the speaker (i.e. your outter door skin), directly behind the speaker.

Look through the speaker opening. See that black thing with the ridges on the outter doorskin? That's a deflex pad. And that's where they are installed.

Therefore Window get's in the way... If I have the window down the deflex pad is blocked.

Nothing you can do about it. But it will help when the windows are up.

Well will that foam baffle work fine? Because using that I don't have to worry about the window being in the way.

is there a difference between Deflex pads and egg shell foam?

I used ensolite in my inner door panels as well... is this considered the same thing? Id like some more midbass from my components.

Yes.

Deflex pads are ridged rubber-type material that are designed to diffract the soundwaves so they do not reflect off of the opposite wall & bounce back to the speaker.

Egg crate foam is designed to absorb the sound waves so to keep them from bounding off an opposing wall and back to the speaker.

Their ultimate goal is the same.....their methods are different and depending on designs/thicknesses/etc could have differing effectiveness and bandwidth which they affect.

Egg crate foam and Deflex pads aren't going to help you with midbass output.

Give details of your install. What mids you are using, how and where they are installed, how well sealed the speaker's frontwave is from it's backwave, power & crossover point/slope, etc ?

I highly doubt you will be able to hear a noticeable difference if you're driving with the windows open.

Im a noob when it comes to slopes and crossover points. So im not sure where Imprint set them at.

Im using Image Dynamics CTX65CS for my speakers. They're installed in an 05 Tacoma, doors are very well dynammated and i also added ensolite foam. I also have 1"mdf baffles behind the speakers. They are being powered by an Alpine PDX 4.150

this is exactly what i did in my setup....
