ik werk zelf ook zonder subs met mijn reveals, maar bovenstaande is natuurlijk beetje vreemd..het maakt wel degelijk verschil of een speaker tot bv 30Hz kan of tot 50Hz ....... of je er wel of niet iets mee doet is natuurlijk een 2e....
over een sub toevoegen: dat is geen kattepis, want je moet dus je monitoring opnieuw afstellen, en dat moet je ook echt goed doen anders klopt er geen fuk meer van je geluid.....want je sub moet nl niet overlappen met je gewone monitors, de crossover moet dus goed worden ingesteld..... maar dat staat allemaal behoorlijk goed uitgelegd in de manual van de meeste sub's.... maar je hebt er dus wel een geluidsmeter voor nodig...
ff wat gedetailleerde info:
"Setting Subwoofer Levels
Once the subwoofer is in position, its level needs to be matched with the near-field
speakers. For stereo systems, the process is straightforward. Obtain an SPL
(Sound Pressure Level) meter. Set the low-pass filter on the KRK subwoofer back
plate to 80 Hz (12 o'clock position) — if you will be using the internal high-pass filtered
outputs from the subwoofer to the near-field speakers.
Now, route 1-octave wide, band-pass pink noise to the monitor system, which will
be sent to the main speakers through the subwoofer or bass-management filters. A
good choice is 500 to 1,000 Hz band-passed pink noise, which is within the fundamental
frequency range of many vocalists, and minimizes high-frequency problems
but doesn't excite the subwoofer. Set this to a comfortable monitoring level.
(Typically 85 decibels SPL using the C response curve on the SPL meter)
Next, route 1-octave, band-passed, bass pink noise to the subwoofer via the same
filter path. A good noise choice is 35 to 70 Hz, which is below the 80-Hz frequency
of the subwoofer high-pass filter, but sufficiently high enough that most subwoofers
will have adequate response in that band. Set the gain of the subwoofer level control
until it matches the same 85-decibel SPL level.
Then, turn up the low-pass filter control on the subwoofer to 130 Hz. This allows
the bass energy between the near-field speakers and subwoofer to overlap. While
listening to it from the console mixing position, route pink noise with a band-pass of
80 Hz to 130 Hz to the speaker system. Have someone flip the phase switch
between 0 and 180 degrees, and then back, and note which position sounds loudest.
The loudest position is correct and in phase. Now return the low-pass filter to
the 80-Hz position (or another frequency if you are using external high-pass filters
for the near-field speakers). Your subwoofer should now be properly aligned for
phase, level and spectral response. "
