10. Adjust the 125 Hz equalizer slider on the Richter Scale
until the Relative Sound Level Meter is reading 0 dB. If you
are boosting any of the equalizer sliders, listen for any
signs of woofer overdrive (distortion, flames, ripping cones
or howling dogs on the next block).
11. Repeat steps 8-9 for the remainder of the slider frequen
cies.
12. Since each equalizer band interacts with the adjacent
bands, repeat steps 8-9 again on all the eq bands from 125
Hz down to 22.5 Hz. Very few woofers can put out a “flat”
response, but try to get less than 2 dB variation from one
equalizer band to the next.
13. Congratulations! You’re done. Now you can listen to the
fruits of your efforts.
APPENDIX A -
Why Equalize?
1. Your receiver is insulting your intelligence. Manufacturers
think that more than two knobs (Bass & Treble) will
confuse you, so they deny you the ability to bring out the
best in your system.
2. Your room is special. Everyone’s is. Speakers have to be
designed to compromise for a wide range of listening
environments. An equalizer can compensate for overly
reflective or absorptive surfaces and help speakers perform
their best.
3. Your speakers can do better. Everyone’s can. An equalizer
can help deepen the bass, smooth the midrange and
extend high end frequency response. After buying a good
equalizer, many audio lovers say it’s like getting a new set
of twice-as-expensive speakers. But for a lot less.
4. The source material isn’t perfect. Did you know that bass is
actually removed from many recordings so they sound
good on smaller systems or over the radio? Used properly,
an equalizer can clean up many of these problems with
the flick of a slider.
