Ha, enjoying the conversation. I have this same DT 600 sub and just last night was commenting on how much bass that it was producing in my small (and lively) HT room (14x14x9) while watching the intro to a Yellowstone series show. I have the sub set up in a corner facing a 1/2 open wall into a larger space. The sub is set to crossover from Elac BS5.2 L/C/R @ 80 Hz with all speakers set to small. Truth be told, we are not bass-heads but do plan to replace the sub with 1-2 better subs. In my conditions however the little DT sub does ok. Eq'd via YPAO on avr.
