Ime acoustic problems call for acoustic solutions, and EQ is not an acoustic solution. Theoretically aggressive room treatment would help in this case. When room treatment isn’t feasible, one alternative would be speakers whose radiation patterns are sufficiently narrow and sufficiently uniform that they do not interact with the room in an undesirable way to begin with.
B&W 705 S3 with bad acoustics
We Recently moved into a new home that has terrible room acoustics, 12' ceilings, tile floors, glass window walls. Open floor plan with no possibility or room treatment. I've never owned B&W speakers curious if they will glare in a very resonate room. Previous tried Kef Rs meta, Dynaudio special 40 and Sonus Faber Sonetto w/ Rel T9x with no luck. Paird with Hegel h390. Auralic streamer.
