Mislim da je vrijeme da vam pokazati projekt za stražnjim zvučnicima;
Zvučnici su "SEAS" - Excel T25CF002-1 ", W18EX001-6,5"
Sve je ručno, nema stroja "CNC".

I have an idea to make a new project to in the base there should be two 10" loudspeakers - just an idea. They look like animals, maybe dinosaurs, but important are 20Hz.

I am approaching to the measurement of the internal volume:

On the last picture,the red line is the waterline

, the vas of cabinet must be fill with water next to it / everything must be perfectly horizontally!/.
I measure the weight of the my vented inner construction - 3.5 kg.
-The amount of water is 42 l. in the box; 42-3,5= 38,5l, 4.5 l more than what's needed - what's next?
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, another W18 EX001.

Let's assume that the density of MDF is 0.75 kg. of cubic decimeter/ average value by tables /. This is 75% of the actual reduced volume.
The reduced volume error is:
3.5 / 0.75 = 4.6 liters actual reduced volume, and the whole volume is 43-4.6 = 38.4 liters.
The total error of 39.6 liters is 1.2 liters or -3.1%.
