Hans, indeed, generally it
it not a good idea to have idea put crossover point in between 2 and 4K but it
is a general rule. That rule that might be very much overridden by a good
practical implementation of a particular installation. To do this “good
practical implementation” you need to have reason to put your crossover at any octave
of your choice. It is hard to me to say anything further as I do not know your reasons,
and not the last factor of my ignorance is the fact that you the drivers about which
I am uninformed.
You are running your JBL
2446 all the way to 2.8K? Would it be because your Radian 475 because place in
a larger horn do not do well 1-2K region? I do not know Radian 475 an only you
can say what drives you. Now, to have 2.8K channel sitting as high (elevation)
as you have in context of nearfields listening is challenging. If you drop your
output to let sat 100Hz then you will need to introduce a larger MF horn for JBL
and that means to move your Radian a few inches up. Will it be a right
direction? With knowing your driver, the way how you do crossovers, your room
and your amplification no one with tell you. Another factor is your
cossovering, only God knows how good or bed your Groundsound digital crossover
is., not to mention that your crossover slopes and filter types are not know.
So, what you need to get
from all of it is that “yes, to put a crossover in the mid of MF is not good”
but it is ONLY if this rule competes with identical in quality of implementation
crossover sensations. Otherwise the rule
defeats itself. Do not pay attention to any rules. Rules are posfactum of consecutive
successes. Make your playback to sound
well and then write your own rules. This is how the things getting done.Rerurn to Romy the Cat's Site
