Nova Utopia Be

sandu · 26th April 2010, 09:59 AM

Hallo, friends!
Until now I was only a reader of this forum.
Now, I decided to ask you to help me.
I finally found the original drivers from Focal Nova Utopia Be (13WX, 6W9451 and TBU) and I intend to build two clones of this loudspeaker.
What I need is the original schematics of the crossover (24dB/oct at 250/2500 Hz). It's true, I tried to calculate them with X-over Pro for example, but I think JM Lab did it much better. So, can anybody help me with those schematics?
Thank you all in advance for any suggestion and good luck!

Hello
I can not help you with the filter but I'll ask a friend engineer can calculate the filter if you want.
By cons I wanted to know where you purchased the loudspeakers, especially the LF-and medium?
Cordially

Thank you for the good intention, "mgmgran". I know the methods used for calculating the crosovers. What I'm trying to do is to make the drivers work on their optimum curves and that's not so easy.
All drivers come from Focal JM Lab.
Regards

Do you have the cabinets built?? You need a set of in box driver measurements before you start the crossover for the system. If you go with their crossovers you are going to need to build box clones with the same driver spacing and offsets and the same baffle widths as an example.

I bought the drivers for myself, not for resale. They are very expensive, but I can advise you by Email how you can buy. I liked the sound and the design and I decided to try. I did it in my own way. All I can say is my mesurements are same to original and the sound is very good. In the end I found the original X-over. Soon I'l post some pictures.
