The 21L2 uses the same drive unit components as its smaller 12L2 brother, with a
crossover appropriately tuned. As a floor-standing model, the 21L2 is capable
of better bass extension than the stand-mount versions, going down to around
35Hz at the bottom end.
and agile, the 21L2 is one of the most musical loudspeakers in its class,
capable of following fast moving bass-lines, whilst retaining full composure
throughout the mid-range and upper registers.
