Positioning (Cont.)
TIP Ideally, the monitors should be placed more than 0.5 metres from the side and rear walls of
the room so that reinforcement and cancellation (peaks and dips) of the bass output caused
by wall reflections will be moved higher in frequency and thus less influential. This reduces the
incidence of ‘lumpy’ or ‘boomy’ bass. Small changes in position can have profound effects on
the bass response, so experiment to find the optimal position.
Bass Response
twotwo series active monitors can produce significant bass energy below the frequencies at
which they become omnidirectional. As a consequence, it is important to consider the effect of
the boundaries of the listening room when placing the monitors.
