Level in dB.
The SuperNova MKV frequency response is limited by the
built-in filter (with an upper end of 150 Hz); for most
applications, the crossover should not be set above 80Hz. It is
equipped with a fourth-order Linkwitz-Riley (24dB per octave)
filter which will block vocals from interfering with its
performance.
When fine tuning the SuperNova MKV, set the crossover to
150Hz as a starting point, you will hear vocals coming out of the
sub; gradually reduce the crossover point until vocals are
eliminated.
