中置音箱是家庭影院中最难对付的一员,难就难在不好配,无处放。现在满街都是家庭影院套箱,成套买、零碎配有什么难的?但你仔细看看就会发现这里的中置音箱大多如老式枕头似的置于电视机顶。广告宣传只强调采用了防磁喇叭,似乎只要防磁就是正宗的中置音箱。其实防磁只是为了不干扰电视机的图象而已,并不是为了多声道声场。真正的中央声道大有讲究。在电影杜比格式中,中央声道主要被用来放置电影中人物的对白。中置音箱放在银幕的后面,全场的观众都能感觉到人物的对话声来自画面人物的位置附近,即所谓的有良好的声画合一的效果。国内的家庭影院很少用得起正面投影电视,都是用彩电作画面设备,中置音箱先天就没有合适的位置。只好放在电视机顶,很多场合都是偏高的。
