Default What speaker wattage?

Ive 50 watts per channel.
What difference will it make if I buy 50 watt speakers or a 120 watt speakers & for the heck of it 300 watt speakers?
Thanks

A basic rule of thumb, you want an amp with more wattage than the speaker requires. You say you have 50w amp. Is that peak power or RMS power? A peak power amp usually supplies about 22w RMS. RMS is the important figure. Thats not much at all.

Its 200 watts peak. 50x4.
Is a 300 watt speaker not going to function properly, or would it last longer ? Is a 50 watt speaker going to blow or not reach peak performance?
What are the pros & cons of big watt speakers vs. small watt speakers
in a 50 watt per channel system.
Thanks again.

Speakers are designed to play efficiently at a specific wattage.

A 50 watt rms speaker will play best given 50 watts rms or higher. The same 50 watt rms will power a 300 watt speaker but, that 300 watt speaker will not sound as good or clean (especially at higher listening levels) as if it had 300 watts rms powering it.

You have to look at the speaker's sensitivity. The higher the number the better the speaker can do with less power. But you shouldn't look at the sensitivity, because it's probably BS anyway.

If you play a speaker very loudly with a low power amp you are going to damage it. That's because when an amp runs out of power it "clips". Instead of sending nicely rounded signals to the speaker, it clips the tops off when it reaches it's power limit ... making square signals. The speaker can't replicate square signals and gets damaged.

Having too much power is rarely a problem, because your head will explode before the speaker will!
