Mackie CR4 monitors through UR22 MK2

I am considering on buying a set of Mackie CR4 monitors to plug them at the rear 1/4 outputs of the UR22 MK2 interface to record with audacity:

I do record and listen to the recording through a set of headphones. However, during playback the sound comes out distorted from a set of external PC speakers. Will this pair of monitors provide a clean playback? Do i need to disable the pc speaker option on the record and playback option on the bottom right corner speaker icon and select the UR22 MK2 device as playback and record so everything runs directly through the interface bypassing the pc audio card?
