You didn't mention your room size. If it's rather small, a good sub will help pressurize the environment. If you want to rock the house, then you'll need either the aforementioned monitors or a pair of large floor standers with a sub for each channel. The system's overall output SPL will decide the effect.
Although acoustic music doesn't go as loud as amplified rock, my large collection of organ CDs will get my Velodyne ULD-15II to rattle the kitchen windows downstairs from 32 Hz down to 16Hz. I can't hear the fundamental but I sure can feel it.
Integrating the sub with the main speakers is a chore though. It's all about balance. But, if you like, crank up the sub!
