How can an amp have different current output with them same "wattage" as a different brand? I would think current output capabilities would go a long way into driving a given speaker. Also it seems hard to get impedance vs frequency curves for a speaker system. Or do I just not know where to look. It also seems that in an effort to boast low frequency response in a single cabinet, we lose efficiency. Am I wrong with any of this? Just curious.
Speaker sensitivity, impedance, and calculating amp power
This is an elementary question, but I'm not quite understanding how to match amp power to speakers. When I searched around on this forum, I found many discussions which went deep into the weeds. I am hoping for a way of calculating the level of amplifier power I need for speakers with different sensitivities and impedances.
If you have the patience, here's the basic question. So, I've learned that one must consider a number of factors to calculate the amount of amplifier power to drive the speaker:
Sensitivity of the loudspeaker
Loss of db at the listening position
SPL desired at listening position
Amount of headroom desired
Most discussion of the demands a speaker will make on an amp focus on the speaker sensitivity. But the speakers I'm considering vary also in their impedance. How would I use both of those factors to estimate necessary amplifier power to drive them with a comfortable amount of headroom?
