Sub in TL

blo06 · 6th July 2011, 01:36 PM

Hi,

I'm trying to figure how to make a sub in a TL.

I thought of it because I want to put it in a corner, with a small footprint and as high as it would, up to the roof.

I have the MJK sheets, but never worked with them : wich one could be the good to begin with ?

What type of TL : ML or QW or ??

What SL/S0 ratio ? I was figuring 1/10 ?

The cut will be around 100 Hz.

Thanks for any idea.

I had asked a simular question few years ago, I remember somebody told me TL enclosure is not very good for making a sub due to the time delay from the open end, it's better to build a horn sub for more spl gain, sealed or passive radiator for faster sound, vented for deeper(I don't agree for the last, but not sure)

All right reserved, I'll keep the final right in explaining what a I said:P

Who told you that crap?
Horns and TL are both efficient designs.

A horn is typically a half-wave or more at cutoff, a TL is quarter-wave or less, so if the rime delay is an issue (for some it is, for some not), the TL has less than half the problem as a horn.

I'm going to model the MLTL first, but where to begin ?
What are good values for "Enclosure Geometry Definition : Model of Internal Air Volume" ?
For QWTL, I use the alignement tables, but for the ML ?

I want to use a JBL 123A.

Hi bjorno, thanks for all !!

I will go deeper in your pict, but first, the last sentence :
"Fs/Qes = 48 suit a closed box (TL not ML-TL)"
Could you precise the braket part : why TL not ML-TL ?

Interesting, to my way of thinking a MLTL is better overall regardless of its Qts when a T/S alignment specs a short vent length to keep vent mach low enough, so what am I missing?
