We get this question a lot: So how to MEP002A units compare to their new generation counterpart in terms of sound level? The former doesn’t have a sound kit (ASK = Acoustic Suppression Kit) and the latter does. Listen for yourself. It is a material difference, but the MEP002A is not nearly as loud as some make it out to be. The water-cooled MEP802A with sound kit definitely quiets the unit down especially at the higher frequencies.
