underseat sub will never have the real thumbing bass of ported woofer box. owned a few under sub due to space issue.
under sub is good for those guitar basses higher low cut frequency, never can produce those real low's with "wooof woooof wooof pump"
under seat sub punch is quick and tight knocks but too boomy when comes to the music 2nd bass.
like a music example electro or trance when the 1st bass hit is a boom sound right? and the right after that 1st boom sound will comes the 2nd bass which is the something like a reflect back organ bass right?
that 2nd bass reflects always plays too high from an underseat sub caused very boomy..
something like a music bassline sounds like this "boookkk whunggg, bookkk whunngg, bookkk whungg"... that bookk is 1st bass, that whungg is 2nd type of bass, and it's that whungg whungg sound comes too high from underseat sub very irritating

yeah a good HU can set all the high cut and low cut vs slope frequency pass to each channel of speakers/audio output, must also depends on your front speakers high cut frequency range start from which Hz, and that HU need set your front speakers so that don't sent the frequency that your front speakers can't handle, this will result your front speaker can focus on playing very loud mids and highs without getting distorted because the heavy bass beyond it cant handle is not sent to it.
too much heavy bass send to the front speakers that it can't handle beyond its range and if it plays too loud will caused it to distort sounds something like "ffrttt frrrtttt frrrttt" something like bocor angin lol
