Adjustable cut-off frequency
➅
An electronic crossover removes medium and high frequencies beyond a point set by the user.
The ideal is to extend the bass frequencies in an even and continuous manner from where the
front system rolls off. In general, a cut-off frequency located between 80 and 100Hz should
be suitable for most systems.
This setting becomes more critical when the BombA is used within a high-end hi-fi system.
The idea cut-off frequency will only be found after extensive listening to a wide range of
musical.

Warning!
Very few recordings possess real bass frequencies. Bass notes such as those found in Rock,
Techno, Ragga music etc. are rarely located within the extreme bass area, but more likely in
the high bass band.
As a consequence, it is recommended to select a cut-off frequency between 100 and 120Hz
for these styles of music. However, you may prefer a lower cut-off frequency for classical
music.

It is possible to set the cut-off frequency anywhere between 40 and 160Hz.
This adjustment should be made in reference to the listening position and with your preferred
type of music.
For a more precise adjustment, your retailer may use an analyzer (RTA).
