You might want to check and make sure that the power amp's output impedance is set to match the driver. If it was set for an 8 ohm load, a 4 ohm driver can cause distortion/clipping at higher levels.
And, besides all that, all volume/level controls/potentiometers on receivers are Audio taper, not linear, so you get most of the increase in the first 1/3 turn.
Most power amp inputs are linear potentiometers though. Most.
