DTQWTII from Argentina

Is this the post you were thinking of?

Another Troels Gravesen's DTQWT Project Build - Page 38 - DIY Audio Projects - StereoNET

After several exchanges of emails with Eminence, the light has come on this subject ....
What seemed like an assembly error of the colors of the terminals (the oring can be exchanged) ended up being a properly assembled and identified speaker, but at an earlier date than the other three I bought ..
The terminals are correct, the pole piece of these models Deltalite II were magnetized neodymium before a way and ultimately reverse, (I am informed that there was a change of magnetizing machine)
 
Latest developments, gluing rear panel, prepositioning of material damping " Acoustilux " of the rear camera. T-Nuts occupy space (1 mm), is necessary to lower the same as previously glued panels. ( More is always better 1.2, 1,5 mm )
Attention to this ! ;)

Do not forget to pass the wires before gluing the traero panel, or we'll be in trouble ....:D

Check the polarity and signal cables bass sector, both are black in this case and can lead to a phase error setting.

Now there is no return ..... closed the back!
I have not used my special presses, this works in the same way and the advantage is that the box is firmly resting on the floor. I think with all this weight is enough!

Screws used to ensure good adhesion at crucial points are replaced by anchors, it is a commitment that I took with handcrafted boxes for speakers.;)

Only necessary will be used to ensure drivers.:)

The rear panel will be painted all black.

Before working with the router on the front panel, do not forget to stick the felt on the top panel. Then it would be very difficult ....:nownow:
So I put the head down cabinets to facilitate the task...:)

As use contact cement, it is necessary to take precautions to prevent stuck in the wrong place. So wooden slat .....;)

With less than before, that's for sure ...:D

Latest developments:

Routing holes for wave guides tweeters, mid-bass speakers JA8008 , acoustic material, etc.
All this was done on the front horn sector.

I think I can make the first hearing in mid-month and starts.

You know, "Man proposes, God disposes" ;)

Closed a box.
Next steps :
Build the base with wheels (this movable base will have only wooden supports, the tips of disengagement are not for me, I do not believe in them)
Painting boxes
Mounting and connecting the speakers ...that will be a rewarding moment ! :)

Wow! Great!
I have a very good feeling: a project completion before this X'mas (navidad)! :)
And... I also don't believe in spikes or similar things. Will sound the same with wheels etc, if don't change the relative height to ground too much, since this is a kind of "load" to the D/TQWT, if I recall correctly.
