SETTING UP YOUR ULTRA SPEAKERS ACOUSTICS (cont’d)
A note about Ultra Tower phase and A/V receiver auto-setup processes.
The Ultra Tower side-firing woofer array is designed to provide a more
accurate in-room bass response than a conventional front-firing tower by
uniformly loading the room, thereby reducing amplitude variations caused by
room modes. Since the woofers are side-firing, the bass at the listening
position is a combination of direct and reflected sound waves.
This may result in a phase warning during the A/V receiver auto-setup
process. If a phase warning is encountered, it does not necessarily mean
there is a problem with the Ultra Tower speaker setup.
While moving the Ultra Tower slightly closer or farther away from nearby
wall boundaries may clear the phase warning, doing so is not required to
obtain optimal bass performance, and the phase warning may be safely
disregarded if the loudspeakers are already located in the preferred room
location.
As a matter of good practice, any time a phase warning is encountered, the
polarity of the wiring at the loudspeaker and amplifier should be double-
checked and corrected as needed.
