Seamless Transition Between Subwoofer and Speakers

The fine tuning process includes

creating a smooth transition of music

between the SuperNova MKV and the

next speaker in line : usually a woofer or

a large midrange. As shown in the

graph across, a smooth transition

between lower and upper bass is

directly relative to the crossover setting

and the capability of the next speaker in

line to reproduce low frequencies.
