Would it go easy to skip the built in filter in my s9500 and run
active crossover with the BSS?

i know there is some JBL filters and some from other vendors for the
K2 s9500.. Would it be possible to success with the BSS unit?

it has a digital input, AES and this is perfect couse i can run it from
my digital AES output on my TacT 2.2x !
