3. In most cases you ll need to adapt your speaker placement to a given room that s less than ideal Here are a few speaker placement basics to keep in mind as you get started A You will generally get the best imaging and other spatial qualities if your front left right speakers and your usual seating position form an almost equilateral triangle with the speakers not quite as far apart from each other as they are from you If you must sit closer to one speaker than the other use the Balance control on your electronics or the individual level controls on home theater channels to give the more distant speaker a balancing boost in volume B Our tower speakers are designed for optimal listening from the seated to standing position For our monitors we offer accessory speaker stands to achieve the right height if you are not using existing shelves or furniture C The best high frequency dispersion producing the widest sweet spot in which you and others can sit and enjoy optimum high frequency definition will result when your main speaker 8 enclosures are positioned vertically rather than horizontally If you are placing your monitors horizontally the speakers will still perform very well but the seating area where you will enjoy optimum sound will become narrower We suggest you position the tweeters to the outside away from the center line You may prefer to tilt the speakers towards ear level D If you sit equally distant
