Project EVEREST DD66000CHAPTER 7Placement and Set-up ConsiderationsThe Project EVEREST DD66000 loudspeaker system is designed to be lessaffected by room acoustics than conventional imaging systems. However, it isvery sensitive to overall symmetry, proximity to walls, ceilings and corners.Ideally, any listening room should contain a combination of live surfaces (e.g.,walls and windows) and absorbent surfaces (e.g., drapes, carpets, upholstery).If the distance between floor to ceiling is low, it is preferable that one surfacehas an absorbent covering. With Project EVEREST DD66000, it is mostimportant to be able to accommodate the optimum listening area that is definedby the 100° horizontal/60° vertical coverage pattern of the horn.In order to obtain the best stereo effect, the speakers should be placed at thesame distance from the listening position.• The distances to the right and left speakers are determined by therelationship between thedistance from the listeningposition to the speakers and theangles of the speakers (refer tothe figure on the right). Theimaging qualities enable thespeakers to be placed relativelyfar apart from each other, butthis weakens center imagingsuch as vocal. By increasingthe inward angle of thespeakers toward the listener will improve the center imaging.• The listener should be centered infront of the speakers and furnitureshould be of an appropriate height sothat when the listener is sitting, the earlevel is on a vertical plane with thehigh-frequency horn (approximately90 cm/ 35.5 in) as illustrated on the right.• The surrounding environment for the speakers affect bass sound quality.Placing the speakers close to wall behind them or side walls bring aboutabundance of bass, but too close distance will result in dull bass. On theother hand, too much distance will reduce the mass of bass but result is in
