Hello forum. I have a pair of KEF LS50 METAs that I use in a 2.0 setup for movies and music, paired with a Denon AVR X4700H. Display is a LG C1 77. I did the calibration where you move the mic to different listening area spots. They sound fantastic. However the dialogue is often difficult to hear in many movies, particularly action ones. The effects/ and other noises often drown out the vocals. It's really annoying to have to make the volume louder in some scenes and then lower in others. I've tried a few different settings on the Denon but haven't had much luck finding an optimal mix. Any thoughts here? Should I be looking at adding an amp or a center? Added a pic of my setup. Thanks in advance. I posted this on a few sites, please let me know if this should be directed elsewhere.
