Do 2.1 Systems Need Bass Management?

AV receivers normally offer digital bass management by default. However, integrated amps and 2.1 receivers rarely offer this feature. Parasound's Halo and Outlaw's RR2150 were all that I could find. Bass management is a must have feature for home theater, but why do companies that make integrated amps and 2.1 receivers avoid digital or analog bass management? 
Because those guys were meant for music, not for explosions et al.
yes,  2.1 systems very much need bass management

Some do, some don't.
