Advanced AcousticWerkez has announced the AAW W500 -AHMorph, the world’s first hybrid with a continuously adjustable sound signature that changes from a combination of a dynamic driver + balanced armature to operating using only the balanced armature drivers.
The metal dial is used to adjust the sound by redistributing power between the dynamic driver and the balanced armature bass/mid drivers, not affecting the high range drivers. When the dial is turned completely counter-clockwise, the dynamic driver operates at full power and BA bass/mid drivers operate at partial power for a slight U-shaped sound signature. As the dial is turned clockwise, the dynamic driver power is gradually reduced, being redirected to the BA drivers.
At the halfway point of the dial, the W500 is at its default sound signature. As the dial continues to turn clockwise, the dynamic driver continues to have power redirected to the BA drivers, and when turned completely clockwise, all power is going to the BA drivers and none to the dynamic driver resulting in a mid-centric sound signature. The sound signature changes are not linear, and moving the dial clockwise from the halfway point will have a bigger impact on the sound signature than counter-clockwise.
This should be interesting and a good comparison for the several other adjustable/tunable options available. The image provided by Null Audio below gives some info and includes pictures of the unit made for THL that will be arriving shortly!
