Dynaudio Sub 6, User Manual, Page: 29 / 35

Each band of parametric equalisation offers three control parameters: frequency, level and Q. “Frequency” defines
the centre frequency around which the equalisation band operates, “level” defines the degree of boost or cut, and
“Q” defines the width of the equalisation band (a higher Q means a narrower band). These control parameters are
illustrated in the diagram opposite.
The Sub 6 Parametric EQ is intended to be used in combination with professional room acoustic analysis to
identify response anomalies, however the Dynaudio Sound Meter app (available free from the Apple app store)
incorporates a real time frequency analyser that can be used to help identify anomaly frequencies and so guide
parametric equalisation set up.
Sit in your main listening position, launch the Sound Meter app and select the RTA option while playing a “pink
noise” signal through the subwoofer (pink noise can be found on many music streaming services). Prominent
peaks in the response curve displayed by the app will most likely correspond with any audible frequency
response anomalies. Equalisation bands can then be set at the anomaly frequencies and the level and Q
parameters adjusted to flatten the response curve.
Further guidance on using subwoofer parametric equalisation can be found on the Sub 6 product page at
dynaudio.com.
Note
The diagram shows one band of parametric equalisation set with a relatively high Q (approx 5) and
approximately 6 dB of attenuation.
Sub 6 Parametric EQ is a powerful tool and it should be used carefully. In the vast majority of circumstances
equalisation should be used to attenuate room anomalies rather than not to boost subwoofer bass. If more bass is
required always try repositioning the subwoofer first.
