请问有没有低功率的大牌音箱 在家搞了个排练房
预算5000左右 100W以下 有时会拿上车上 所以不能太大 家里搞了隔音 不过也不能太大声 http://bbs.guitarschina.com/redirect.php?goto=findpost&pid=19691631&ptid=1165345回复 3楼 疯狂的和弦 的帖子
我们都知道,电子管的电功率和音量不成正比关系,也就是说电功率减小一倍,声功率减小并不多。这就给我们选择衰减器带来了很大的不便,不同的功放音量不完全相同,而衰减器只能按电功率衰减来标定,如何建立电功率和音量之间的一个关系,如何利用一些简单的方法就知道应该选多大的衰减器。下面来看这个表格40 watts is 94% as loud as 50 watts.
30 watts is 86% as loud as 50 watts.
25 watts is 81% as loud as 50 watts.
22 watts is 78% as loud as 50 watts.

20mW is 10% as loud as 50 watts.
10mW is 8% as loud as 50 watts.
