Supernova MKVI & MKVII Manual    13

Now  that  you  have  corrected  the  phase  of  the 
subwoofer(s),  the  next  step  to  room  correction  is 
setting the room equalization. 

To  properly  set  up  the  room  equalization,  you  will 
need  a  Spectrum Analyzer  or  the  following  rule  of 
thumb:

Boosting the response at 20Hz is very demanding for most subwoofers. The Supernova MKVI and 
MKVII series is designed to take a boost at such low frequency. However, if you are using the IQ 
amplifier to power another subwoofer, please consult with your subwoofer maker to determine if 
their subwoofer can withstand a boost at such low frequencies.
