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.
