Joe Carter Posted February 20, 2021 Share Posted February 20, 2021 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. Quote Link to comment Share on other sites More sharing options...
mustang_flht Posted February 20, 2021 Share Posted February 20, 2021 Hi @Joe Carter This is what the panel does not retract on Heresy III and Heresy IV, because the speakers are mounted from the front. So to access the interior of Heresy IV you have to remove the bass speaker. look here https://blog.son-video.com/2020/03/test-klipsch-heresy-iv-lenceinte-compacte-3-voies/ 1 Quote Link to comment Share on other sites More sharing options...
OO1 Posted February 20, 2021 Share Posted February 20, 2021 the Heresy 1 was not a sealed cabinet , and the woofer-midrange-tweeter were mounted from the inside of the cabinet------the Heresy 4 is a sealed cabinet ---with the drivers mounted from the outside Quote Link to comment Share on other sites More sharing options...
wuzzzer Posted February 20, 2021 Share Posted February 20, 2021 Only the Heresy I and what is sometimes called the Heresy 1.5 have cabinets where the entire back comes off. The II, III and IV only have the input terminal cup that's removable. 1 Quote Link to comment Share on other sites More sharing options...
