I brought up this old thread for reference purpose.
I got a new question.
Using JBL2123J in the mid horn does not give me the large stable "sweet spot" I hoped for even though the sweet spot is larger than my previous stereo had. I have tried to use the crossover with the inductor L2 with value of 2.0 mh or without. I like it without the L2. But these did almost nothing to increase the size of sweet spot. I wonder if you could enlighten me as to where the problem is and what the correct approach is to tackle this problem. I am also inclined to take the easy way out by purchasing a pair of Delta 10A and follow your crossover schematics without any modification. But I like the JBL2123J drivers a lot and really am hopeful that somehow I can keep them in the corner horns.
