My Allison ones lived with adjacent wall placement for 13 years in my first house, which was a small high ranch with a finished basement…… Beggars can’t be choosers. The basement is where they resided, although it was finished and had a fireplace down there so some of those music sessions were quite nice, my sweet spot was a couch facing into the corner of those adjacent walls.
The corners eluded me because both speakers were too far away from either corner to take take advantage of those sidewall reflections. All being said still sounded pretty sweet
