does a resitor give you more watt?
what does a resitor do?

No, but it dissapates power. Either reducing the power to the load (speaker) if it is in sereis, or, if it is in parallel, increasing the power consumed without necessarily changing the power to the load.

A resistor is like a kink in a garden hose. The more you kink the hose, (the higher the series resistance) the less water flow is realized at the end of the hose. (the load, speaker, etc.)

A shunt resistor (across the speaker) on the other hand is like a hole in the garden hose. The bigger the hole, (the lower the resistance) the less water flow at the end of the hose.

Curt could have added that unlike inductance and capacitance, resistance is (essentially) independent of frequency, dropping or shunting the same percentage of what passes through it the same amount (percent of signal) regardless of the frequency.
