Crossover Specifications

Built-in Crossover

A crossover is a type of filtering system that permits only certain frequencies to play. A Low-Pass (LP) crossover allows only frequencies below its setting to get through which is good in the case of some subwoofers. A High-Pass(HP) filter allows frequencies above its setting to pass through, this is normally used on speakers.

When a crossover is set to FULL it means no filtering is added and the full frequency spectrum is allowed through the amplifier. Filtering is important because feeding a speaker frequencies it cannot reproduce effectively creates distortion.

Low-pass (LP)
High-pass (HP)
High-Pass Crossover Frequency
The high-pass crossover frequency can be a fixed crossover point or a variable crossover range. A variable high-pass crossover allows you to select a specific crossover point which allows frequencies above the set crossover point to pass, while making frequencies below the set point gently or harshly roll-off, depending on the steepness of the slope.

The steepness of the roll-off slope is measured in dB/octave and refers to the rate of attenuation (lowering of volume) outside their pass bands.

65 - 5400 Hz
Low-Pass Crossover Frequency
The low-pass crossover frequency is typically used for subwoofers. It can be a fixed crossover point or a variable crossover range. A variable low-pass crossover allows you to select a specific crossover point which allows frequencies below the set crossover point to pass, while making frequencies above the set point gently or harshly roll-off, depending on the steepness of the slope.

The steepness of the roll-off slope is measured in dB/octave and refers to the rate of attenuation (lowering of volume) outside their pass bands.

40 - 4600 Hz
Max Output Level
The maximum level (in volts) of signal output. A higher level will increase the clarity and boost your signal.
9 volts
Frequency Response
The range of frequencies the speaker will reproduce (lowest frequency to the highest). Bigger is better, meaning the wider the range, the better. The optimal range is 20 - 20,000 Hz (which is the range of human hearing).
5 - 50000 Hz
THD (Total Harmonic Distortion)
The amount of change in harmonic content of the signal as it is amplified. A lower figure indicates less change and a more accurate amp. THD below 0.10% is inaudible.
0.01%
Signal-to-Noise Ratio
This spec compares the strength of the signal to the level of background noise. A higher value indicates less background noise.
95 dB
Width
The width of the item from left to right (side-to-side) measured in inches.
8-3/4"
Height
The height of the item, measured from top to bottom, in inches.
1-1/2"
Depth
The front-to-rear depth of the item, in inches. If the item is angled or slanted, this value is the bottom measurement.
6-1/2"

Great Value and Plenty of Features

January 31, 2015

I found features on this unity that more expensive 1s don't have, like constantly variable phase shift for the sub channel. This feature really brought the sub to life. I was able to place the sub sound exactly where I needed it.

Great piece of kit

November 17, 2014

I will recommend this to any one .what I love the most is the band pass feature that brings smoothness to the mids. I will put this above the expensive audiocontrol 6xs and expensive modules.

Rodelio P on Oct 23, 2014
I have a stock head unit and my amplifier and subs are connected via speaker level inputs. Can I run rca cables from the input on the amplifier to the input on the crossover and have it work?
