AudioControl Store

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".

The Epicenter - Bass Restoration Processor

AudioControl's legendary bass restoration circuitry, The Epicenter, brings out the best bass in any system. Whether you like rock, jazz, hip hop, country, banda, classical, CD's, MP3's, or cassettes, you will love how The Epicenter makes your system sound. More Bass... Louder!!

The unique bass restoration circuit of The Epicenter, originally patented by AudioControl, looks at the low frequency harmonics that are in the upper frequencies and uses them to recreate the lower bass fundamentals that have been compressed, rolled off, or simply removed. The chart Linked Here shows what it does for the signal. What it does for you, is provide deep earth-shaking bass that you've never heard before.

Key Features:

Patented Bass Maximizer™

The Epicenter contains a bass maximization circuit that accurately recreates and injects low frequency information back into the signal path. What that means in everyday terms is that The Epicenter will give more bass impact to your best compact discs or even your old tapes. US Patent #4,698,842


What’s the use of having good bass if you can’t control it? The Epicenter has a unique equalization circuit that contours the restored bass to your speaker system.

Dash Mount Control

The Epicenter is designed to be mounted anywhere in the vehicle, with the exception of the front bumper or radiator. It comes with a dash mountable control that allows you to enjoy the effects of The Epicenter without having to leave the drivers seat. The dash mount control also has a dual color LED indicator that can be rainforest green or sunshine amber. This LED will grow brighter as you add more bass or dimmer when you decrease it.

Bass Maximizer Indicator

Not only does The Epicenter Concert Series provide magic to your ears, but it also gives you some visual enjoyment as well. On the chassis of The Epicenter is a backlighted logo that flashes when the bass maximization circuit is activated. Special effects in your trunk!

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?

Bass Output Control

The Epicenter circuitry has the ability to produce large amounts of deep, mind shattering bass without damaging your speakers. The Bass Output Control circuit allows The Epicenter to maximize the bass output of any autosound audio system while restraining destructive bursts.

Speaker Level Inputs
Speaker level inputs are commonly referred to as high-level inputs and vice versa. This input type allows you to get your audio signal directly from the speaker wire in your vehicle, instead of using RCA cables. The advantage of this is factory integration, as most stock radios do not have RCA outputs to run amplifiers.
Output Connection Type
This is the type of output that the unit accepts.
Maximum Input Voltage
This is the maximum voltage that the processor is able to accept.
9.5 Vrms
Maximum Output Voltage
This is the maximum voltage that the processor is able to output.
9.5 Vrms
Adjustable Center Frequency
This function allows you to adjust the center frequency of the signal proccessing.
LED Indicators
This refers to any LED illumination present on the unit. This includes Power Indicators, Clipping Indicators, illuminated logo's, etc.
Illuminated Logo
Bass/Gain Remote
If the unit comes with a bass/gain remote you will be able to control the level of your bass from your dashboard. Typically bass remotes also include a 16-20 ft. wire for installation.
Auxiliary Input
This refers to whether or not the unit has an auxiliary input for connecting additional accessories.
Total Number of Inputs
This is the total number of input connections that go into the unit.
Total Number of Outputs
This is the total number of output connections that the unit will produce.
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 normally used with subwoofers. A High-Pass(HP) filter allows frequencies above its setting to pass through, which is normally used with speakers.
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 - 22,000 Hz
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.
130 dB
Total Harmonic Distortion (THD)
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.

great buy

March 25, 2017

I would recommend this product to anyone professional or amateur who loves car audio and need a great bang at a reasonable price .I installed this epicenter to work with my RE audio xxx 12inch sub and a hifonics monoblock amplifier. Not only did it meet my expectations but surpassed them as well it replaced those low frequencies that could not have been heard otherwise in my R&B tracks but it also inhanced my bass all together .I can't picture ever having a system in my car without audio control epicenter being a part of the set up.its easy to intall but a bit tricky with the actually tunning of it but what I found worked is to set both the knobs in the center it sounds great there then you can play with it as time goes by until you get the hang of it .thanks sonic for sending me another great product all the way here in sunny Barbados .

wish i would have bought this a long time ago

October 26, 2016

after all this years of being into car audio i never used an epicenter. I herd my friends knockoffs and didnt sound good to me so I never bother. I decided to give the audio control epicenter a try since I have used other AC products.when i first hooked it up i was impressed with the bass and how hard it hit. It took my oldies and spanish music to another level and alternative music. for those that say that it takes the bass on songs thay already have bass thats because of the subsonic filter but once you swapp it out for a lower filter it does make a difference. also note that it has to be tune properly otherwise it will get your subs stinky.
