Relationship between power amplifier and loudspeaker
This is not easy to calculate. Professional audio, the power amplifier is dual-channel, and the 350W one can only push two 350W or even 300W speakers. For professional audio, the power ratio between them is 1.5: 1, or even 2: 1, and the power of the amplifier is always greater than the power of the speaker. Few civil power amplifiers have so much power.
