This Mid-Tweet replaces the original "FriedEgg" speaker in the Advent LA and New LA speaker. I was suprised as it is a true Remove/Replace speaker. Not like the previous xxxx-19. You do not have to route out the opening to accept the larger round magnet. The leads have the push/pull connectors. You do have to re-drill the 4 screw holes, as this faceplate is longer. The sound is awesome. Mids are expanded and the highs are seamless and higher than the original. A great upgrade to the Advents.
