Using Three or Four Fathoms
Research indicates that the
smoothest bass response for a large
listening area can be achieved using
four subwoofers, placing one at
the midpoint of each of the four
walls (although using two or three
subwoofers can be almost as good).
Experimentation with
subwoofer and listener
placement is recommended to
achieve the best results – the
benefits can be substantial.
High-resolution measurements
and professional system calibration
are recommended for the best possible
results & system performance.
