Phase Warp
The Phase Warp is a variable control used to adjust the phase of the out-
put signal relative to the phase of the input signal. This "phase alignment"
is most noticable when used with an array of woofers whose vertical or
horizontal planes are staggered (not eminating from the same point.)
Adjusting the Phase Warp can electrically realign the signal fed to each
woofer as if all woofers were aligned on a common ZDP. In SPL systems,
a desired ZDP (Zero Delay Plane) is the point source where all speaker's
voice coils are aligned on the same imaginary plane, thus allowing the
signals to arrive at the microphone at the same time.
The phase warp is most noticable when the system is playing a sine wave
(test tone), not music. When used with the proper test equipment, this
feature can increase the relative SPL in a system.
If the Phase Warp is not used (like with a competitive SPL vehicle,) each
amplifier's Phase Warp should be set to (0˚) or (-).
