What you do need is good tuning options so that your front speakers is optimized. The simple removal of the 80hz filter to an head unit set 50hz is enough bass extension for most people.
sometimes when we'd like to have bass, all we need is a tweeter it sounds crazy but it was discussed in wiredstate where sir hansen mentioned:

"The distinct sound and timbre of "bass" instruments as we know it - be it different sized drums, organs, bass guitars, synths etc are not purely bass frequencies but have significant amount of midrange and treble frequency content. It does not increase bass quantity per se but it does increase bass articulation, clarity and intelligibility because the added treble results to a more accurate recreation of bass timbre."
