I'm sure this question has been asked and answered before, but I couldn't find it in a forum search.
I'm looking at building the above system and want to know how to go about building a crossover. Would I be right in assuming a crossover freq of 400Hz?

Hi Rob,

There are different ways to make a crossover. Usually there is no filter used for the full-range driver, only for the bass. To protect the full-range driver at higher volume then it would be wise to add a filter.
For the FE206E I would suggest a 1st order filter by using a serial capacitor of 33-47uF which reduces the too strong lower midrange enough and sets the crossover frequency for the bass at around 220Hz.
For the bass I would use a passive line filter as suggested by Frode. The values needed depends on the LaScala you have though, which driver is used in there and how the resulted response is in your room...
Ciao,
Bert

Thanks Frode and Bert for your replies.
In suggesting a passive line filter, do you mean bi-amping, or am I misunderstanding you? Is there cct diagram you would recommend?
From the research I've done I'm thinking of using K33s in the La Scala clones.
Thanks
Rob
