Turn off your HP, set your LP initially to 80Hz and play around with it until the sub blends well with the front stage...80-85Hz would be about the limit.

rule of thumb for highpass (subsonic) is 3/4 of tuning:

0.75 x 34 = 25.5 Hz

for low pass, start around 80Hz and tune by ear.

I can't turn off the highpass i dont think? subsonic filter?

you can turn it off, look in the manual

but the lack of a subsonic filter is going to leave your sub helpless below tuning.

it will reach full excursion very easily (as if in free air) and could damage the sub.
