To tell which series (MK1, MK2, or MK3) your BASSBOSS Loudspeaker is, take a look at the power connector.
MK3 Series Loudspeakers:
If your power connector is a PowerCON True1, then you have a MK3 series loudspeaker. It will look like the image below:


MK1-2 Series Loudspeakers:
If your power connector is a PowerCON (meaning it has a blue locking power connector), then you have a MK1 or MK2 series loudspeaker. It will look like one of the images below. Pay particular attention to the power connector, the plate may look slightly different. Note that there is not an easy way to tell the difference between a MK1 and a MK2 unit, so typically we just specify "Pre-MK3" and "MK3."
