2-way Tops with RCF N980

Llo all,

I'm pretty new on the forum. So i'm just gonne ask my question and see if there comes an anwser

I want to build two 2-way top speakers. Why, you say?
I was lucky to find myself 2 RCF N980 drivers with EV HP94 horns and i want to make good use of them
And, I also like a good challenge.

They will be used as FOH for my coussins rock band. At the start accompanied by 2 mackie SRM1800 Subs, but i would like to build 4 cubo18's afterwards.

Here are my first questions.

- How to determin what bass drivers to use (branche? 10",12",... ? Power? 1 or 2?)
- How to calculate the volume of the speaker (I would like them not to big for transport reasons)
- Whats the best way to determin the crossover freq. (I have a DriverackPA with RTA mic at my disposal for testing )
- Should i go for passieve or active filtering.

As you see, i've got tons of questions.

I will be drawing the speakers in 3D Inventor. Not only the sound matters

I hope you guys can help me along the way with this project.

Kind regards,

Kris
