The B4 is unbelievably versatile: high-pass and low-pass 1st/2nd/3rd/4th-order filters in 25Hz increments from 25Hz to 6375Hz. All discrete (Toshiba Jfets), no opamps or IC’s.
I have three speakers and would leave the tweeter passively crossed. But on a scale of 1 to 10, how hard is the B4 to use for beginners? Would the learning curve and/or functionality of this one be a easier?
