On the graph horizontal upper scale indicates the impedances of the headphones in ohms, which are connected to the amplifier. The right vertical scale indicates the voltage in decibels (dBV).
You can see point in the graph. This point is the recommended voltage level for AKG 712. It is 13.6 dBV (4.7 Vrms) on the vertical scale. AKG 712 reproduces a sound at 90 dB SPL at 13.6 dBV input.
We see point above maximum level for AE-5.We can not get a louder sound in the bundle AE-5 with AKG k712 pro.
But, each man lisen different music and lisen of different volume, optimal for him. One human say - AE-5 with AKG 712 pro is a loud bundle, another human say is a quiet bundle. Who is right?
More precision answer can give compared known bundle vs AE-5 with AKG k712 pro.
Example, we have got
X-Fi (base model),
iPhone 5S and
Audio-Technica ATH-M50,
Kennerton Odin MK3,
Sennheiser HD 600
Add this models in graph and choose «Max» option.

How to understand dB?
You can play sound in foobar2000 and use volume control in "dB" in player.
