In summary, a subwoofer enables realistic reproduction of the fundamentals of certain musical instruments. The cost is system complexity, including the addition of an excellent room EQ to achieve frequency response flatness in the 60Hz – 135Hz range. If missing this mark for the fundamentals of a few notes at the lowest end of the scale is not of concern, then you may decide to forgo the complexity and cost of the subwoofer and room EQ for music reproduction. To achieve the full range and power of all acoustic instruments necessitates a subwoofer. The NHT B10d at SECRETS is a welcome adjunct to reaching this goal.
