有源式超低音音箱MAGNAT QUANTUM 731A
无论是外观还是音响效果,这个音箱都是以小型音箱 MAGNAT Quantum 音箱系列为基准
而 配套设计的 。当 然您也能将其与其它音箱组合使用。
连接音箱系统时,请您注意先关掉所有的机器,将所有音箱接线的正负极连接正确,即各个
输出的正极与各个输入的正极相接,负极与负极相接。另外还请注意遵守接收器/放大器和音
箱的使用说明书的各项规定。
放置
人的耳朵是无法测定超低音音箱播放频率范围的方位的,所以它的放置位置通常比较随便。
不过我们还是建议将它放在听者的前方与前置音箱的附近为宜。此外您还应该注意它与两侧
和后方的物件或墙壁的距离至少要有20厘米,否则会影响低音播放的效果。
