WOW: WOW is an award winning stereo enhancement
technology that significantly improves the performance of stereo
(non-surround sound encoded material) signals through any two-
speaker system. It extends the sound image in both the horizontal
and vertical planes well beyond the speakers themselves. In
addition, WOW incorporates TruBass and SRS Dialog Clarity
Enhancement. When TruSurround XT accepts a stereo signal,
WOW is enabled for a better listening experience.
Finally, you may optimize TruSurround XT for your particular speaker
system.TruSurround XT will give you the best bass response according to
the size of your speakers, so take a quick look at your speakers and “size
them up.” Then, under the section “Speaker Size,” drop down the list of
selections.
Generally speaking, larger speakers produce lower frequencies.When using
large speakers or ones with a subwoofer, using the lower Hz selections
between 40Hz and 150Hz usually produce the best results. The setting of
“Small 250Hz” should work well for most computer speakers (or “Small
100Hz” if using a subwoofer), though some experimentation won’t hurt at
all. For each category of speaker size, Small, Medium and Large, you will see
several “cutoff frequencies” shown in “Hz.” Again—the larger your
speakers are, the more ability they will have to handle the lower cutoff
(bass) frequencies.
