Thanks for your reply. But it seems I copied the wrong parameters (sorry for that). They were for the 15-4 S. The right theile below. That might work better with the lower Xmax? The plan is to use this Kick as a low mid driver in combination with a Cubo 18 and a mid/HF cabinett on each side ran on Lab 4000, Lab 2000c and Lab 1300c.

OK, that's a better choice. Let's not pin it down on one parameter though, like Xmax, although an u0 over 3 % is a good indicator for a 12" or 15" kick driver.

Hello there, would Fane Sovereign 12-300 work in Cubo Kick 12? Or other from Fane product range. Looking to use 12-300 in cubo 12's and want to build kicks as well, sticking with the same manufacturer. Not sure what parameters are crucial in kick design. thanks!

I would go with the 12-300 for both Cubo 12 and Cubo Kick 12 (higher efficiency/ lower Qts works well in both designs).

Those are oki for sure,
The RCF MB15N351 has been optimized for mid-kick, the only draw back might be the light-ish cone, I would put a lot of dampening material on the walls of the rear chamber (just in case).

The Celestion FTR15-4080FD is an allround driver, whether it's bass, mid or kick, it should feel right at home.

In 2020 I've built two Cubo Kick 15 based on 18Sound 15ND930 for a venue in Leipzig.
Now that we have events again I can say that I am very happy with these speakers and I would say the build was a success.
During this build, I recreated the drawing by Cubo in Librecad to figure out some dimensions I could not discern from the drawing and to decide on details like where to put terminal plates and mounting holes for the speaker or the rear wall.
Maybe this can also be helpful for some other people who are building Cubo Kick 15, so I decided to share these drawings.
The proposed locations dimensions should provide clearance for Adam Hall 87160 Terminal plates and 18 Sound 15ND930. For other drivers/terminal plates, your mileage may vary.
