As always, there is no order between the photos and the work sequence, know how to apologize.....

Tools are pretty fine, but too much quantity of them are only necessary ifyou job with them, for the enthusiast is too much. The brush, looks good. I have one at father's house one of them from grandfather's. But my taste went to electronics, not carpenter or teachers like my parents. I broke the mold of generations of doctors, teachers and shoe maker/repairers.
It appears that you are fan of Racing Club, no? Nos tienen de hijos :-(

I also study electronics and I am a graduate of CAT, but finally I dedicate myself to sales. The swings of the country .....
And yes, the nickname is for The Academy and the year of my birth.
Are you our neighbors from Avellaneda ?
Yo tambien estudie electronica y soy egresado del CAT, pero finalmente me dedique a las ventas . Los vaivenes del pais.....
Y sí, el nick es por La Academia y el año de mi nacimiento.
Ustedes son nuestros vecinos de Avellaneda ?

Yes, but not necessarily to live in Banfield you have to be from the local club, I would have to be from Tigre and see that I never went to watch a Racing game. It is very far away. Pending subject.....
Sorry OT
This calculator has confirmed that I will have what I am looking for when the boxes are finished.
I have played a bit with the different variables calculated by introducing Delta Pro 18 A data and the results have been excellent for me....

Results for 20 hertz to 1m / 1 w without room gain, two 18-inch speakers: 104 db
Every meter that we move away is - 6db, so at a distance of 3 meters (my listening point) I will have -12 db, that is, I will have 92 db, nothing bad without EQ or DSP ....

The calculator says only "driver diameter in inches" I guess there has to be a small difference, but it will not be significant, but it would say "effective diaphragm diameter " or something like that .....
" This calculator can solve for one piston excursion parameter while changing the other variables. For example: tell the calculator the number of drivers, cone diameter, desired volume level, a frequency and it will calculate how much driver excursion (Xmax) is required to achieve this assuming a sealed box or infinite baffle alignment."
Notes:
basic piston formula:
SPL = 112 + 10 * log(4 * pi^3 * Ro / c * (num * Vd)^2 * f^4)
Vd = (.83 * diam)^2 * pi / 4 * Xmax
This calculator is only valid for sealed box or infinite baffle alignments.
Xmax excursion is center to peak ("one-way") which is usually half of the peak to peak value.
These are excursion limited numbers. It is assumed that amplification and driver power handling are not a factor.
Vented alignments will typically have double the driver's Xmax values at F3, this shows the efficiency inherent in the vented alignment.
Isobariks should be calculated with half the number of drivers, since all we are interested in is how large the radiating surface is and how much air it can move. Isobariks change effective box volume and that is not what is of interest here.
If you're interested in some basic dB doubling laws then check out my dB laws, misc formula, and tidbits page.
These equations don't follow the max 194dB limit in 1 atm. They track nicely until you get to the extremes (example: 10000 drivers or an Xmax of 300 feet or a driver with a diameter of a quarter mile). As things get huge the point source model falls apart.
How did you get to 38.90 cm, with or without the wing ?

Emphasis mine - I assumed that "piston" referred to the moving area of the cone, ie SD in the TSP's, not the whole diameter of the chassis.
As for the 38.9, that's just 2*sqrt(SD/π).
Ahhh, trolito?
no, in any case old troll
no, en todo caso viejo trolón ....
Introduces 15.3 inches against 18?
I do not see that right, but thank you and leave it there.
you will still need some power to get them to that level of excursion in that size of cabinet. some equalization will likely be needed to level the responce, as 100db at 20 hz is likely to be 130 at 80. for example.
room gain will give some linear boost for the lower response curve. but still you will need to equalize up the lower end and turn down the overall volume, or equalize down the top end and turn up the overall volume. both mean the same thing, some equalization, with a equalizer to attuente the higher to match the lower or boost the lower to match the higher.
A diagram could explain well. But im too lazy.
