Crossover filter adjustment
The purpose of a crossover circuit is to filter out a specific range of frequencies from a
speaker’s input to maximize its performance. For a tweeter, the goal is to filter out low
(bass) range frequencies to maximize the high range (treble) response. Conversely,
for a subwoofer, the goal is to filter out the high and mid range frequencies, leaving
only low frequencies to play through the woofer. There are two kinds of crossover
implementations, active or passive:
Active Crossover
This filters selected frequencies before the audio signal is amplified, between the
source unit and amplifier. Our built-in crossovers are an example of this type of crosso-
ver.
Pros:
By removing unwanted frequencies from the signal before it’s amplified, your output
becomes more efficient, only working to amplify the desired range of frequencies.
Cons:
By removing unwanted frequencies from the signal before it’s amplified, you are
dedicating those filtered channels to only provide a certain frequency range.
CONNECTORS DEFINED (CONT.)
The built-in active crossover is adjustable from 50Hz to 250Hz, using either a low-pass
mode (bass only) or high-pass mode (lower midrange and highs only) to easily maxi-
mize your speaker efficiency.

Note: when using any 6.5” to 8” speakers, the recommended
settings are high pass mode with the frequency filter set at or
above 150hz.
