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

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.
20 watts is 76% as loud as 50 watts.
18 watts is 74% as loud as 50 watts.
15 watts is 70% as loud as 50 watts.
12 watts is 65% as loud as 50 watts.
10 watts is 62% as loud as 50 watts.
9 watts is 60% as loud as 50 watts.
8 watts is 56% as loud as 50 watts.
7 watts is 55% as loud as 50 watts.
6 watts is 53% as loud as 50 watts.
5 watts is 50% as loud as 50 watts.
4 watts is 47% as loud as 50 watts.
3 watts is 43% as loud as 50 watts.
2 watts is 38% as loud as 50 watts.
1 watt is 31% as loud as 50 watts.
3/4 watt is 28% as loud as 50 watts.
1/2 watt is 25% as loud as 50 watts.
1/4 watt is 20% as loud as 50 watts.
1/10 watt is 15% as loud as 50 watts.
50mW is 13% as loud as 50 watts
20mW is 10% as loud as 50 watts.
10mW is 8% as loud as 50 watts.
5mW is 6% as loud as 50 watts.
