So, who to believe? They all can't be right, can they? Danny at G-R Research showing they are definitely tilted toward the lower mid-bass in frequency response
For this purchase I'm going with Erin since his subjective opinion is backed by objective measurements. DR at GR did not definitely show any such thing. Erin's Klippel measurements show a pretty good bass response. I doubt DR knows how to read klippel measurements. I take nothing this guy says seriously. If you feel the need to fiddle with them perhaps replace those iron core conductors with air core. I understand these are $1500 speakers and I'm not at all sure how they will do in my room but I will measure them with REW for any needed EQ as well use my usual suspect list of tracks. Using a little EQ in roon is cheaper than switching amps.
