i’m thinking that these speakers are very close to new-as in not fully broken in. the first day had me wondering, they had a “transistor radio” edge that was somewhat prominent- some minor position tweaking and a day and a half of steady music, and what seemed like an am radio now sounds much more like a near electrostatic level of crisply articulated detail. no trapped back wave bouncing around inside a box to disturb the subtle stuff that is so valuable! i’m also getting more low end. these very low mass cones are free to do their thing. 4’ from the back wall, 7’ apart, listening from a bout 8’ away, medium toe in.
