I received my long awaited book and disc this Friday and spent a few hours this weekend reading listening and moving my heavy JBLs into the room and found the place with the most even bass sound. Then I found the sweet spot and adjusted toe-in. There I stopped and I am very pleased by the results. As our couch can’t be at the exact distance from the speakers because then it’ll block a door I decided to apply my Linn DSM’s space optimisation where I input my seated position. The software would then adjust any standing waves for where the couch is. It works excellently I can tell you. Music is now huge and coherent and musical what you have. Thank you PS Audio. I still have the depth adjustment part left but no hurry with that.
