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.

Best regards Cubo

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).

I have a few RCF MB15N351.

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).
