适于分布式声音的扬声器布置
由于分布式声音为遍及某一区域的一般声音,因此应尽
可能均匀地布置各个扬声器,使该区域的各个位置声音
覆盖达到均衡。
将左右两侧的扬声器摆放在距主要收听区域距离尽量相
等的位置。
为避免产生音量过大的“热点”区域,应计划使用更多
的扬声器,并将各个扬声器的音量调低。
双声道立体声扬声器布置
将左右两侧的扬声器摆放在距主要收听区域距离相等(或尽
量相等)的位置。各扬声器距其最近的侧面墙的距离也应尽
量与该等距离接近。

等距
理想情况下,左右两侧的扬声器之间的距离应比其距主要收
听区域的距离稍短。
家庭影院扬声器布置
左前和右前扬声器应放置在视频显示器的两侧,其高音扬声
器应尽量处于与耳朵相近的高度。
左前和右前扬声器应相对靠近视频显示器的两侧。例
如,当视频显示器为 50 英寸(1.3 米)时,左前和右前
扬声器相距一般不应超过 80 英寸(2 米)。
中置扬声器应与视频显示器的中心对齐。其高音扬声器
应高于或低于左前和右前扬声器的高音扬声器的距离在
2 英尺(0.6 米)内。
即使将前置入墙式扬声器安装到比耳朵更高的位置,JBL
HDI 波导也能维持均匀的声音传播,为听众呈现优质的聆
听体验。如此一来,用户可以更加自由灵活地按需布置
扬声器。
