Taking out my SMD CC-1 to change my HPF from 125Hz to 80Hz @ 24dB slope for my HAT 6.5 Clarus components. Hopefully they don't distort and become muddy at high volumes.
My RF T800.4-ad built in crossover is at 24dB slope. The DC5K is also 24dB built in. But yeah, I'm using the same slope. Just going down to 80Hz from 125Hz cause I sometimes listen to my fronts with no subs turned on.
