Take the sensitivity rating of the speaker, which is expressed in decibels (dB) at 1 watt/1 meter. If it's listed as an in-room or half-space spec, use that number. If it's an anechoic spec (like the ones found in some actual speaker measurements) add +3 dB. The number you have now will tell you roughly how loud the speaker will play in your listening chair with a 1-watt audio signal.

What we want to get to is the amount of power required to hit at least 102 dB, which is about as loud as most people ever want to enjoy. How loud is that? Ever been in a really loud movie theater? A properly calibrated theater running at reference level will give you about 105 dB per channel. That's very loud — louder than most people want to listen to — which is why theaters rarely play movies at volumes that high. So 102 dB makes for a good target.

Here's the key fact you need to know: To get that extra +3 dB of volume, you need to double the amp power. So if you have a speaker with an in-room sensitivity of 88 dB at 1 watt, then 2 watts will get you 91 dB, 4 watts will get you 94 dB, and so on. Simply count up from there: 8 watts gets you 97 dB, 16 watts gets you 100 dB, and 32 watts gets you 103 dB.
