Hi!
Dear Cubo I have question, - very important to me.
Thank you for your time if you would like to help me.
I plan to make a Cubo Kick 15 and want to use one of those speakers Beyma 15QLEX1600Fe or OBERTON 15NXB1200 (or maybe another from OBERTON?)
Which speaker do you think will be better? I want to widen the frequency response a bit up and down.
And the secon question:
Can I make two front skids (two pieces) slightly bent like a moon or should they be completely straight as in the design?
Hope you can understand what I mean.Thank you for answering.
Please advise if this is a good choice? Here are the parameters:
