is a subwoofer for LFE still necessary if one has a pair of fronts that will go below 20Hz and above 20KHz in HT application

No speaker in your sig reaches that deep. What are you looking at?

the question was not referenced to my setup, just a general one

When LFE is routed to the mains, the explosions used for effects can require upwards of 500-1000 watts to reproduce at reference levels. Few stereo/multi channel amps can handle these transient peaks like a dedicated sub amp can. It really puts your tweeters at risk when the amps clip due to loud sound effects.

I even cross some bass out of my largest towers for movies since it colors the mids and highs when the low stuff is induced into the track.

The term "full range" is used loosely to indicate most music tracks, not movie soundtrack effects.
