This is the driver.
It has not very long stroke, but this still moves pretty much air:)

This is very impressive. I really like the internal shape of the "boxes".

Where in this beautiful country are you located? Do you accept visitors? :)

I feel like I'm crawling in the mud with my beyma 12br70 t-tqwt's compared to you. How did you plan your corner traps?

Thanks for the nice feedback
I come from Langesund, also called sunshine coast. Here are the doors always open for visitors

Area marked with yellow is completely filled with glava. The bottom (concrete) and all walls in the sub is covered with 50mm rockwool

Same here mate. My next design will definitely lead down to the 10 Hz region within a +/- 3dB division.

Have measured 10Hz-11Hz-12Hz-13Hz-14Hz-15Hz-16Hz-17hz-18Hz-19Hz-20hz-22hz-25Hz-30Hz-35Hz-40hz with the same volume.
Can probably say that this goes totally in the basement:D
Level within +/- 2 dB
