Bass Shape Control
The rolloff rate and the shape of the low-frequency
corner of a subwoofer affect its sound. For example, a
subwoofer with a “soft” corner and a gradual rolloff rate
below its range of operating frequencies will gener-
ally give a tight and rhythmically “fast” character. A
system with a low-frequency corner that is squarer
and rises slightly before falling off quickly will provide
a more robust low-frequency sound. Additionally, the
faster rolloff will give a better compromise in terms
of apparent bass output versus woofer power capabil-
ity. The Snell XA 75LE via the remote control. Some
people prefer the “Reference” position for music and the
“Cinema” position for movies. Try either setting and use
whichever one suits your mood, your room acoustics, or
your program material.
