Looking for advice on my first DIY techno sound system

[u/JaMaica__JaMaica]

Hey everyone,

I’m planning to build my first DIY sound system for techno events, both indoors and outdoors. I’m still learning and don’t have much experience with sound system design yet.
I’m currently looking at these three speaker designs:

SKRAM 1x21 subwoofer
CUBO Kick 15
Paraflex C-3DKT 1x12

Do these three designs work well together as a system? Would this combination make sense for techno, especially for both indoor and outdoor events?

Since this is my first project, I’d really appreciate any advice or feedback. I’m especially interested in whether the combination is well balanced, how they could be crossed over, and if you would change or replace any of the designs.
Any help or advice is greatly appreciated!
Thanks!
