To determine if your speakers are full-range or not, you must look at the minimum
frequency response of your speakers. The concern is not the high-end of the frequency
response, but rather the low-end. As noted above, if your speakers are not rated for a
minimum of 20Hz, then they are not full-range speakers. Here are some considerations:

Assume your speakers are not full-range. Modern speaker design uses a
subwoofer to handle the relatively small percentage of content you hear in an
audio signal. Low frequency content, more commonly known as sub-bass, is
greatly amplified by the subwoofer, which explains why the smallest percentage
of your audio content can often be the loudest. The subwoofer allows the
speakers to concentrate on the remaining 99%+ of the audible frequency
bandwidth.

Generally, if your speakers came with a subwoofer, they are not full-range
speakers. As noted above, subwoofers are designed, in part, to allow speakers
to stay clear of the low frequencies. When examining the specs of the speakers,
make sure to look at the frequency response specifically of the speakers, and not
just the specs of the speaker system. Sometimes, the most easily available specs
may include the subwoofer, which can go as low as 18Hz +/-2 dB; the
minimum frequency of the speakers, however, may be much higher.

If you have a 2.0 stereo setup, look for the frequency response specs. If they do
not have at least a 20Hz to 20kHz range, then they are not full-range speakers.
You may try full-range, but you will lose any audio data below the minimum
frequency of your speakers or may hear distortion at lower frequencies.

Headphones tend to be full-range speakers, as they are designed to operate
without a subwoofer. However, the quality of your headphones will determine
whether you should configure them as full-range or not.

If you use a receiver or your speaker system is run through your subwoofer, do
not use the full-range setting in the Creative panel without consulting the
instructions for your receiver or speaker system, since it's possible that your
audio system prefers to be set to full-range, so that the receiver or speaker
system will utilize its own crossover settings once receiving the full audio range.

Lastly, audio equipment quality will have the greatest effect on whether you
should set full-range, or not. Very few speakers are properly designed for full-
range audio, and if they are, then they will likely be very expensive.
Two last considerations: First, do not set Headphones to full-range if using the SBX
Surround option, as Surround will not work properly in full-range mode. Second, do
not enable full-range mode for 5.1 audio or the bass redirection will not work properly.
The only exceptions to 5.1 and full-range is that you either 1) have a full or partial set of
