1. A laundry treating appliance, comprising:
a structural support;
a laundry holding system including a rotatable treating chamber;
a motor operably coupled to the rotatable treating chamber;
a suspension system operably coupled to at least a portion of the laundry holding system and suspending the laundry holding system from at least a portion of the structural support, the suspension system having six natural frequencies including three translational frequencies and three rotational frequencies, the suspension system includes at least one spring that is configured to group the three translational frequencies and three rotational frequencies into a first group determined by a predetermined first rotational speed range of the rotatable treating chamber or the motor and a second group determined by a predetermined second rotational speed range of the rotatable treating chamber or the motor that is separated from the predetermined first rotational speed range, in this manner the first group and the second group are correlated to known speeds that can be accelerated through during a cycle of operation; and
a controller configured to accelerate the rotatable treating chamber, via the motor, to a rotational speed above the first group and the second group.
