I like all these mltl designs and made a pair myself
from some measures graciously provided by GM.


It's not clear if yours is the triangular version of
the Jordan TL or a triagular mltl. How and
where is the port located? Downfiring out bottom?
How long?

Mine is a 6 in. extended out the bottom. The driver
is the modest but hard working Fostex FE127e.

The sketch is just a mock-up for an MLTL with trapezoidal cross-sectional area, downfiring vent, and raised on stilts. The bottom piece would ideally be something heavy, like concrete or what, for stability.

My "logic" is that if the height of the stilts is at least as large as the diameter of the vent, the tuning of the enclosure ought not change (or in any event would be LOWER than designed, which is better than the opposite).

The basic concept is a wall-hugging design that toes in the speakers roughly 45deg, as recommended by Messr Jordan. The base could even be offset by about 3/4", to clear any floor moulding, ensuring closest wall-hug. Just keep the wall between the speakers relatively free of clutter for best stereo imagery.

Morning all,

I did write that last message in rather a rush so probably didnt come over too well.

I have found MANY referances and things to read up on while ive been researching this enclosure and i have found the mathcad files and intend to have a play. I havent had a chance yet cause im at work on an oil rig in the middle of the north sea and they dont like you installing programs on there PC's ! I get to go home today (weather permitting (sunshine makes lots of offshore fog!))after 2 weeks so i intend to try them out while at home.

GM, can i ask are you saying to stay with a small port but to have it downwards firing or to have the bottom open as a large port?

Ill be back next week with lots of questions about how the hell to use mathcad.

Thanks

Wella

Hi,
have a look at this thread.
19 Hz TL

I don´t claim these links are essential discussions but read a few of those carefully and you´ll have a good start with mathcad.
(+of course Martin´s site itself and Bob Brines)
Besides the forum is full of advice and designs made with mathcad from the pro´s. Always good to "re-simulate" in order to understand the changes talked about in some discussion.

I got many different designs for the FE-167E in my mathcad folder which I have from Bob Brines site, this and other forums.
Can make them into jpg´s if you want and send them over.
Those include TL´s, BR´s and a voigt pipe (cain abby clone;see forum)

greets&happy reading

Just a graphics hint... gifs make a lot more sense with this kind of material.

Before you do this,
there are a number of known problems.
You´ll find a few discussion/solutions here in the forums.
Do you use Norton Internet Security? If so then you might have to turn it off.
