Edit- amp is 12db per octave but HU is adjustable from 1db to 24. Seems to fill the holes better. 1

Anything about aprox 60 deg is painful so I can tell you it's less than that using the hu crossovers.

Hence me bringing it up. Why would the amp need to work harder to process a signal that's already been processed by the hu? In my mind it would be doing less work? 1
