For over two decades, AudioControl has been designing and manufacturing award-winning autosound products at our factory located in the rainforests of the Pacific Northwest. During this period, countless sound-off winning contestants have chosen AudioControl products to give them the competitive edge. "Can you really win without AudioControl", was part of an article written commenting on competition winning systems. Nothing sounds better than an awesome recording played back on a kickbutt system. Unfortunately, the acoustics of your vehicle can take away from your systems performance. While AudioControl products do not change the laws of physics (although they act like they do), autosound enthusiasts have long known that AudioControl products "make good stereo sound better"

6XS - 6 channel Electronic Crossover

The 6XS does it all. Sharp 24dB/octave Linkwitz-Riley alignment crossover with remote level control for the bass. Automode™ input switching automatically configures the 6XS for two, four or six channels of input with up to eight channels of output. Includes bass management with the Programmable Frequency Match (PFM) circuit and a high tech PWM power supply for maximum voltage in all conditions.

When using an electronic crossover in your system, one of the most important considerations is the type of slope. Lesser quality crossovers will cause phase shift errors, speaker crossover nulls, and improper speaker performance. Like other AudioControl crossovers, the 6XS contains an audiophile 24 dB/octave Linkwitz-Riley alignment design that provides linear phase response over the entire audible frequency range.

Key Features:

AutoMode™ Inputs:

Whether your source unit has two, four, or six outputs, the 6XS will automatically switch the inputs to match.

24 dB/Octave Linkwitz-Riley Alignment Crossover:

The programmable 24 dB/Octave audiophile caliber crossover in the 6XS is the same topology as in many other award winning AudioControl components. Needless to say, it is a far cry from the wimpy crossovers that find their way into many amplifiers these days. What is the benefit of fine tuning your system if you cannot accurately route the proper frequencies to the proper amplifier channels?

Remote Mounted Subwoofer Level Control:

Need a little more bass to impress your buddies? Or maybe you want to tone it down to not scare off your date. Whatever the case, the 6XS has a subwoofer output level control that allows you to control the amount of signal that goes to your subwoofer outputs. In addition, you have the ability to mount the chassis of the 6XS in the rear of the car (we recommend staying away from the bumper), and mount the dash control in some easily accessible location. The dashboard of your car comes to mind.

13 Volt Pre-Amp Line Driver:

The 6XS offers a high quality line driver that takes the low output voltage of a source unit and increases it up to 13 volts peak. This allows you to maximize the signal-to-noise of your system and drive your amplifiers to their maximum output without clipping. No hiss, clicks, or pops plus maximum sound quality.

PFM Subsonic Filter:

This unique feature is legendary with many AudioControl fanatics for its ability to fine tune the bass response of any system. Why waste power on nasty subsonic information when your Programmable Frequency Match (PFM) filter can help you clean things up?

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.

250 - up 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.

30 - 250 Hz
Built-in Bass Reconstruction
Bass reconstructors, or bass enhancers, improve low frequency reproduction in a car audio system with at least one subwoofer. These bass expander products will help your subs produce accurate bass thumps.
Line Driver
A line driver is a small amplifier used to support the strength of the audio signal coming from the source unit.
Equalizer Frequencies
The frequency range that allows control of the center frequency of each equalization band.
15 - 3500 Hz
Max Output Level
The maximum level (in volts) of signal output. A higher level will increase the clarity and boost your signal.
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).
10 - 100,000 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.
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.
110 dB
The width of the item from left to right (side-to-side) measured in inches.
The height of the item, measured from top to bottom, in inches.
The front-to-rear depth of the item, in inches. If the item is angled or slanted, this value is the bottom measurement.

Great crossover and line driver. Definitely noticed great clarity with my system and the amplifier gains were turned all the way down which meant that the line driver was superb!
This made a huge difference and would enhance any system.

Bandpass Filter for midrange which makes it easy to use more power on a specific frequency range.

Distortion was a minimum even when the head unit's volume was all the way up!

High quality "guts" and great build quality.

Would require different chips if you need to change the cut-off frequencies.

Highly precise Processor

August 11, 2010

This crossover is just sonically precise without the clicks, hiss and buzz in your music. It has frequency chip that you can build and install to comply with your system needs. It also has a line driver that takes low voltage passing through and boost them to a more higher voltage so your music is clearer and brighter. It's the best

3 Way 24 dB Active Crossover with Rear Ch.

September 7, 2013

24 dB Active Crossover with Front, Rear and Sub inputs for 6 ch. or use just Front and Rear for 4 ch. or just use Front for 2 ch. input. Auto mode circuitry will feed the Sub from the front ch. inputs. Crossover frequencies can be changed from 15 Hz to 3500 Hz. Purchase already made up, array of resistors, and just plug them in. Gain controls for each frequency setting. Easy to set up. Clean with no noise. Use passive capacitors to protect your tweeters from low frequencies due to amp turn on etc.
