fuckin handles. I thought you had some Jedi trick with three ports.lol

Hello again!!!!

Nope sorry not the local meca judge down here.That's Arian. Here's where I started, it won't be fun unless you get it easy, would it?

good luck reading guys!!!, that's basic theory , then there's advanced lol

@airbone

I have somthing of that sort for you.It's called an Aperiodic Bi Chamber enclosure.It uses three ports and two chambers , which adds a second resonance in the enclosure's pass band.

I have always been interested in boxes like this. I might have to try something like this

[shogen]

box looks great... I usually don't use handles .. I'm too much of a man, if kickin' it don't make things work I'd be fcked!!! lol

on a side note... those handles are a great idea ... !!!

jesus, I scanned over it and figured out something. That I don't understand it.lol

Hello airborne,

The ABC enclosure is fairly simple and yields great results. I've tried it on many occasions with good success.It works by adding a second resonance in the enclosure's pass band thus reinforcing a high, low and center frequency.Just like a ported box, you have roll off on all the ports and chambers, so it evens out response along the intended range.You can tune it to peak at one frequency for spl, gain a maximally flat response for sound quality or give a response right in between the two.

There's a simple and accurate guide to getting it done^^, and it can form the basis for alot more, once you learn how to use it effectively .Give it a try, you may be surprised at what they can accomplish.

shit man, I am going to give it a shot when I finish up my camaro. That guide looks like it was designed for a pair of subs I have.lol

[revoracing247]

cool to see im not the only one who tries to read those research papers on that site and use horn resp.

for the compression chamber did you find the response you got from your model in horn resp to closely resemble how it preformed in real life?

i am just worried about designing one with a compression chamber in horn resp and then spend all the materials to find out it's nothing like i predicted.

Hello,

The major part that hornresp does not account for is cabin changes and gains.The program can fully model an enlcosure in an open air environment, wall loaded and multiple stack system, but lacks input parameters for cabin loading, which is basically a box in a box lol.

The other part of my design process is more or less experience to know what, where and how.You can easily tailor an enclosure there, but then with enough experience you can shape the enclosure's response around that of the cabin.

You may need to spend a good amount of money for materials for trial and error, but in the end it's pretty much worth it.

In other words, there is no exact science behind it, and my response is predicted accordingly.
