Jabo KH50 Horn, experience?

Dear People,

First of all sorry that this is in English, my German is simply not good enough. I hope though that you guys can help me.

I recently bought a Jabo KH50 horn!, I'm very excited. Now, I had contact with Jabo and they advice the BMS 4590 or Altex 288 K driver (which they is better than the BMS). I was wondering who has experience with these horns and which drivers you are using and what the results are.

Another thing is the Bass driver and cabinet and crossover. Any tips and ideas are welcome.

I have the feeling that I started to build a very nice system and I want to gather as much information as possible.

Thanks you all,

Jacob
