Hello, I have discovered a nice loudspeaker at the Montreal Hi-Fi show and I am already thinking about cloning these when I will finish my Zen V4. The sound was exceptionnally good.
Do you think this is a ML-TQWT?

What do you think??

What do you think??
I think that the Qts of 0.21 for the FE-166E is too low for a ML TQWT, I would recommend the FE-167E. If you use the FE-166E the bass will be very weak. The Qts for the FE-167E is 0.31 according to the Fostex data sheets. The FE-164 also had a spec Qts value of 0.31 but I measured them to be closer to 0.35. The FE-167E is a much closer match for a replacement driver for my ML TQWT enclosure design.
Martin,
Thanks for the advice.
Thats even better, the FE-167E is shielded.
And it isn't that expensive, $63 usd per driver at madisound. I think its around $120 cdn at Solen.
Considering I need no crossovers or other drivers than this one.
Francois,
Any ideas how high the Abby is? They say the driver is at 39" height, and by looking at the pics I'd estimate the height to be 73".

Thank you MJK, we appreciate your expertise. I will follow your advice on the driver.
I am more interested to clone the appearance and use a well known (and simulated) design (especially from you). This is a good start to learn about these kind of loudspeaker.
Ilianh, Solen sell them for 120$ CAD. That's not so bad to appreciate the sound of a full range driver in a TL.
The speakers was a bit taller than me so I guess it is around 70-75''.

Before they were famous
Here is a link to Mr Cains DIY effort before he went pro.

I would suspect this is very close to what he is now trying to sell to others.

Hi Ilianh,
Those sims look very promising! Three comments :
1) The slight peak at the bottom will not be as pronounced in reality. The MathCad model does not account for the seperation between the driver and the port so some additional phase shift will exist rounding this little nasty off.
2) That is a very tall ML TQWT. If you were to make the port a little longer you might be able to reduce the height. I like the 4" diameter port you are using, it will greatly reduce the possibility of any port noise (I have not noticed any in my 3" diameter ports but it is better safe then sorry).
3) Please call me Martin, Mr. King is my dad. My kids make me feel old enough as it is so please refer to my dad as Mr. King and me as Martin. 8^).........
Hope that helps,

Thanks for those comments on the sims,
I was wondering about the slight peak, but you answered my question before I even asked
Also, your right about the size, I'll try to make it 60".
Francois,
Of course, thats important.
I need to make myself a Speakerworshop jig and to aquire the drivers.
All I need now is.. money..
Otherwise I'd have the drivers now
And I'm wondering, whats would be better for this project? hardwood? (cedar?) or MDF? I think hardwood looks way better than MDF/veneer.

I guess its worth it
But I dont think for the front and rear panels 10" wide would be enough, or if it is, the whole thing has to be deeper (more than 10" deep) , in order to make a 7xSD (930 cm^2) base.
Is there wider hardwood boards? I'll check in the Rona near my place.
I have never seen 4'x8' hardwood panels, so maybe another alternative could be some high quality (marine grade?) plywood(oregon pine?). Ever seen any?
hehe, well thats what I meant, big panels (made out of smaller ones).
Anyway, what do you think of the high quality plywood idea?
Other than that, there isnt much choice..
The maximum base area we can get out of 10" panels is 5.4sd
that would mean, if we keep the same ratio, ~0.7sd / 5.4 sd.
I have to make the port around twice as long to compensate, I dont see any bad sides of this.. but.. I'd want to hear Martin's opinion before proceeding
I dont see any specific phase problems too..
heres the sims of that ratio and port lenght
