I received a pair of JBL 53-5333 active crossover cards for the 5235. They came with resistor networks for 120Hz, 500Hz and 800Hz and 24db slope. Lowpass delay is selectable 350us and 700us. Is there any advantage over the passive cards with 12db and 18db slope ? I plan to use these to biamp my 4333.
