How is the power range determined?


Let's say that you have a floor standing speaker with the freq. resp. 30-20KHz, 8 ohm impedance, and 90dB sensitivity.
How would you (or the manufacturer) determine the power range of the speaker?
Is there a way to determine the optimum amp power for the speaker?
If the speaker manufacturer states the power range as 50~300 Watts, if price and size don't matter and everything else equals, would you rather go for as much power as possible, or would you still try different amps with different wattage to determine which amp would be best for the speakers in your room?

My rule of thumb with "normal" speakers (6 to 8 ohms, 86dB to 91dB)is to use an amp with 30% more watts over what the mnfc recommends. Dali recommends a max of 150w for my Ikon6 towers. I drive them with a 2 x 200w Aragon 4004 MKII. There is no doubt in my mind that the Ikons could easily take 300wpc if played at reasonable volume.
