The world is saturated with subwoofers, many of which have a peak in frequency response to enhance movie sound tracks at the detriment of music. Tuned to have a bandpass response, the movie-inclined subwoofers limit the low frequency extension at usable SPLs. The frequency peak may persist, even if a first-class electronic room EQ is in the loop, especially if the room is sized and the subwoofer is positioned so a modal resonance peak occurs near this frequency. Here, we review the NHT B-10d, which has a 10" woofer and 300 watts of BASH amplification.
