Terror bass 500 and OBC115

[Bill Fitzmaurice]

Just to make it more confusing: We loudspeaker engineers don't use watts, we use volts. Power delivered varies with current, current varies with impedance, and the impedance of a speaker isn't constant, it varies with frequency. An average 8 ohm rated speaker will have an actual impedance between 5 and 50 ohms, with the impedance being different at every frequency. At equal volume your amp can be putting out 200W at 50Hz but only 20W at 100Hz. We use volts because they're constant into any impedance load, allowing us to accurately calculate a speaker's mechanical limit. 

 

And 1+1 doesn't equal 2. Take a look at Ohm's Law and you'll see why. For instance, 28.3 volts into 8 ohms is 100 watts. You'd thank that 56.6 volts would be 200 watts, but it's actually 400.
