Box design for CobraStatus - Tline IN THE TRUNK

[fritosaregood]

It's a 1/4 Wave flared vent T-Line. I've had a little bit of practice with this type of enclosure with great results. There is a loading chamber, compression chamber, expansion chamber, and acceleration chamber. The specs are left with CobraStatus since he paid for the design, but all chambers are tunned at 39hz

What do all those chambers do?

And to me it looks like this will be tuned really high as a tline, since an expanding line needs to be longer to get the same frequency it would of a straight line.

Unless it acts more like a ported box

but my first attempt at a tline was really fudged but it ended up being a great box with a pretty flat response

the problem is that what your doing isnt exactly the correct way to do it...what your thieory is trying to do is make a tapered horn/folded horn. when for that to be true the whole port would gradually get bigger as it came to the exit of the port...

while your design will work, its not exactly the way that its meant to be done and i can understand why considering its greatly harder to taper it all the way through then to have sections like you do that are the same width for a moment before getting larger.

I like doing my tlines like this, but in actualaity its a horn

Azn got it right. A trick I tell few people, well, 2 people tonite that I keep remembering and forgetting, as azn said, it doesnt have to be a 1:1 ratio, but what works best, is when you find Vas, and that Vas equals the area in the tline, well, as far as 12" subs go, you have an absolute perfect tline/horn

I honestly think this looks good, but may be more based on a higher tuning, than a daily tuning

can you explain a little more,

Vas is volume isnt it? not area

[Decaf]

he meant volume... when the vas = the t-lines displacement

techincally he was still correct in wording too.. since he said the area in the t-line, not the area of the t-line
