OK. So you get a pair of speakers to your house. You set them up. Move them around. Find the "sweet spot". Decide these ARE the speakers for you! They sound just perfect in YOUR house in this room. You are SOOoooooooo glad you went the audition in YOUR home route.
Something suddenly happens and you have to move everything to the spare room or the finished basement. OR you suddenly have to move. What good did it REALLY do to audition and pick out the perfect speaker for YOUR room?
