Clearly, we need more universal definitions of some of our terms. Most people hear are talking about frequency response, while I know that some also use slam to refer to things more along the lines of macro dynamics, punch, bass impact, presentation style, etc. Since this post compared the LCD to ALL iems, it clearly isn’t referring to tonality.

Also, iems can be pretty reasonable in these categories, and in some regards, the LCD slam is nothing special compared to focals, again, depending on definition.
