Can a large speaker fill the room and be accurate as well? Oh my yes. Take for example an Apogee Duetta Signature. Tall (5 foot)planar two way that goes for about $1400-1800 around here. Will most definately fill the room with sound and can be astonishingly accurate from the upper bass on up, especially on vocals. Bass easily extends into the 30 hz range but is best used with a GOOD sub and a GOOD electronic x-over (like a Marchand or Bryston)to cut the lows off of the bass panel. Several subs have pretty good internal electronic x-overs with transparent high pass sections.
Properly set up and fed (which your 4B-ST is certainly cabable of doing) you'll be glued to your seat and wittness to an at times breath taking musical experience.
