Hello,
I woud built a TL with a PL18WO09 4ohm version + XT25TG !
I have mathcad with the worksheet. I designed a box with the offset driver in an open ended TL worksheet.
PL18 4ohm T/S
The box :
it will be a tappering TL .
L = 50inc
offset : 0.2 ( 50*0.2 = 10inch )
So=4*Sd
Sl=0.5*Sd
I got this SPL curve :
What do you think about it ?
Can I desing a TL with the worksheets with 2 driver ? If yes, how ?

Sim looks good. Your taper is 8:1, which might have the vent opening too small (port noise due to high velocity). Line start (So) for this driver should be no more than 3*Sd.
To model two identical driver in one box, double the Vas and Sd.
Hello,
sorry for the late respons, just I think on it how to do it !
I see this MLTQWP desing :
Here
I can desing the same in the ML TQWT worksheet if I set the
Z driver and zport from the distance of the begining of the TL line ?
Like the "zport" will be near the same far from the begining of the TL line as the lenght of line.
I attached a picture, I woud a straigth desing.

An externally hosted image should be here but it was not working when we last tested it.

Thank you, that is very cool ! On my other computer I desing with mathcad an MLTQWT for the PL18WO09-04 and it is much better than with any other worksheets. straight and short TL line is enough, and I can use 2 driver in a normal sized box. I will post it on sunday... until I have no mathcad :-S And ofcourse thank you the table how to change the T/S parameters with 2 driver !

Your speaker drawing looks correct but the submitted FR plot says nothing apart from the supplied dimensioning i.e. the power level and excursion is left out.
I checked your design and came to the conclusion that it only would be ok and not sub-optimised if your maximum SPL requirement always stays below about 90 dB.
Hint: For better performance, double the port diameter and increase the speaker volume and length in order to lower the port air velocity.

HEllo,
Thank You for your help you are true !
I redesign itt a little with more carefull for the other curves. Enlarge the port diameter and the length of the port and a little the so sl. Do not the L of line, If it is working I woud built a smaller box. I will run this speaker with maximum 35watt RMS power.
I attached the file that I saved from mathcad, it is easier !
