floor (anywhere from 8 feet to 12 feet) corresponds to the
wavelength of sound from about 92Hz to about 140Hz.
A very easy way to very quickly set-up the bass is to use a sound
pressure meter. Even a smart phone with a sound pressure app
will work as we need to set relative level. We recommend using
test tones at about 300Hz and 60hz to rough the system in.
Play the 300Hz tone, and measure the sound pressure level at the
listening position. Then, play the 60Hz tone and adjust the BASS
GAIN until the sound pressure level matches the 300Hz tone. Next,
adjust the LOW PASS setting to mirror-image the BASS GAIN.
If, at this point, it does not have enough mid bass (male singers
sound too skinny), turn the low pass up slightly or alternately
position the speakers closer together in order to achieve better
lower midrange coupling between the main speakers. If he sounds
too fat turn the low pass control down slightly or adjust the gain
down.
When you have had a bit more time to know your speakers better,
you will be able tailor the sound of the G4s to your preferences. In
the meantime, you should already have a flat in-room frequency
response after this step.
Imaging and Soundstage
While imaging and soundstage are controversial subjects (how do
you ever know that the soundstage is recorded correctly in the first
place??), it is vitally important to our enjoyment of a recorded
musical event. The G4 is able to deliver a realistic soundstage only
if the recording contains such realism.
If your vocal selection is a well-recorded audiophile CD or LP, the
performer (assuming that he or she is not very close miked) should
appear to come from between and behind the loudspeakers and be
at the appropriate height and size for a standing person. If it is not,
there are several remedies that will address this.
If the voice is shifted to one side (left or right), move the speaker
which the voice is apparently closer to slightly (about ¼” or 6mm)
backwards until the voice centers. You can also move the speaker
which is apparently further from the voice forwards the same
amount.
