Hi, I have a curiosity question. I have a pair of Heresy IVs and I’ve noticed after seeing photos of earlier editions of the Heresy with their rear panel removed. It seems they have a series of screws that can be removed in order to access the back of the speaker. My IVs have no such screws. There are screws on the plate holding the binding posts and there are screws on the port. Does this mean the back panel cannot be removed easily? If so, is this unusual? Keep in mind I have no reason to take the back panel off, I’m just curious.
