I want to show you how I find the volume of the rear speakers.They have a complex form and the introduction of data in the appropriate program will take a long time, after assembling of the cabinet i do additional processing and here the math does not help.

From waste material I made this gadget ,that takes part in the measurements and when assembling the cabinet:

I prepared the two shells in this way;

I fill the cabinet with water to the red line / there ends the front panel with the speakers /.

I find the volume - 43l, I deduct the weight of the internal ribbed - massa 3.4kg.
And the net volume of the cabinet is 39. 6l. More than I need, I need about 32l.
The problem is that my investor likes the vision of the column.The decrease in volume must occur inside the construction of the cabinet.This sends the project in a more initial phase,we have a new requirement for the project, second W18 EX001.

Wow! That's great work. They're beautiful. Are these ported out of the bottom?

There is no hope for this project to be completed soon, because I decided to change the project to the rear speakers and make them three- way;

PS
In this way i releasing a pair of speakers 18EX..., I will need them for another project.a pair of speakers 18EX, I will need them for another project.
