I’ve owned the special 40’s. They work quite well with Jazz, classical, and most vocal instrumentation.
Electronic, rock, hip hop. Yes. They will play. Though they do not accelerate well with that style of music. At least that was my experience. Pass labs xa25, Herron vtsp line stage. I have zero treatment in my room, with the exception of wall to wall office carpet for my entire apartment. Maybe it helps. Maybe it hinders. Went back to my old speakers. My little part of the world is good now.
